* Fixed #101 - Warg Dash not beginning run action when used.
Timer interval, Waterball, Crimson Fire Formation and boss walk delay updates
- Reduced the timer interval from 50ms to 20ms (official value)
  * For a long time it is well known that the Aegis interval is 20ms, but devs have been hesitant to set it to that out of performance reasons; these days however, machines are better and there aren't really many 2000+ player servers anymore, so a 20ms interval is actually quite viable now.
  * Setting the interval to 20ms makes the server perfectly in sync with the client that expects the server to have a delay of no longer than 20ms.
  * All skills that are "chain-able" on official servers will now also be 100% chain-able here (previously it just worked to 40%), assuming there is no lag
  * Skills with cast time will no longer go off 30ms later than officially
  * Several others improvements in regards of client-server sync (timers are used almost everywhere)
  * This might increase the CPU usage by up to ~50%, if you have trouble running your server with this, you can increase it again in timer.c (TIMER_MIN_INTERVAL)
- Strongly improved the Waterball implementation (bugreport:9382)
  * The interval between Waterballs is now 150ms (previously 125ms); due to the timer interval it will alternate between 140ms and 160ms (yes, this is official)
  * While the Waterball effect is active, players and non-boss monsters can no longer walk
  * Added a server-sided canact delay each time a Waterball is shot, which is equal to the one the client gives; this is to prevent hackers from being able to mass-cast Waterball; you can still multi-cast Waterball if your aMotion is shorter than the Waterball interval (i.e. 186 ASPD or higher)
  * The Waterball effect is no longer canceled when the target hides behind an obstacle, but no waterballs will fly and no damage will be applied; walkdelay will remain, but there won't be any canact delay for the caster (meaning he can cast another spell); if the target comes out of its cover during the duration, it will be hit again (this also fixes an exploit against MVPs)
  * Waterball now has a max duration of 10 seconds, even if more water cells are available, the effect will stop; this means that level 10 monster water ball will now only hit up to 67 times
- Fixed Crimson Fire Formation having a knock-back effect although it shouldn't (bugreport:6949)
  * It will hit once every 20ms with no knock-back, regardless of whether the target is undead, non-undead or a player
  * If you want to it to display more "fluently" you would need to set the SKILLUNITTIMER_INTERVAL in skill.c to 20ms, but the performance loss is pretty big for something only this skill and Firewall would benefit from
- Bosses are now able to ignore skill-induced walk delay (#100)
  * They can for example walk after casting Sonic Blow and Waterball (see above)
- Minor description improvements
- Fixed item bonus for vesper card in pre re
- Fixed warning for infinite warp where count_rewarp increased when the player was warped near a warp

Land Protector, Ground Skill Splash, Storm Gust Knock-back
- Land Protector now behaves like on official servers (bugreport:5237)
  * Land Protector now protects from units being placed on it, no matter if they have splash range or not
  * Land Protector no longer protects from damage from units not outside Land Protector that splash inside
  * Meteor Storm no longer shows meteors falling if they would land on Land Protector
  * Pneuma can no longer be placed next to Land Protector
  * Also cleaned up the code a bit, so the checks are done where they should be done
- Ground skill splash ranges updated to their official values (bugreport:5237)
  * Lord of Vermilion places units in a 11x11 area with 3x3 splash range each
  * Storm Gust places units in a 9x9 area with 3x3 splash range each
  * Heaven's Drive places units in a 5x5 area with no splash range
  * Venom Dust now has a splash range of 3x3 and is consequently larger than before
- Storm Gust's knock-back behavior updated to official (bugreport:5237)
  * Each of Storm Gust's units will knock back "Away from center"
  * As units in the south-west are processed first, the knock-back direction will usually be north-east
  * At the edges the knock-back direction will be "to the outside"
  * Land Protector and Ganbantein will influence the knock-back behavior strongly, e.g. if Storm Gust has a hole in the middle, it will have a "suck in" effect
  * Added a config option for those who want the old "random direction" behavior from eAthena
Fixed dialog in quests/eden/eden_quests.txt

Fire Pillar, Acid Bomb fixes
- Fire Pillar can no longer hit plants (follow-up to https://github.com/rathena/rathena/commit/04a1173f7d4c0e1ffbace05d34d8b60dfd037a94)
- Acid Bomb will now hit every 500ms instead of every 1000ms on renewal (related to bugreport:6338)
Magnum Break damage fixed

Autobonus on ground skill and Angelic Ring fixed
- Autobonus3 will now also trigger when using ground skills (bugreport:6434)
- Fixed trigger chance of the Angelic Ring auto-bonuses (5% -> 10%) and that they didn't display any effect
Assassin Cross of Sunset updated
- Improved formula of Assassin Cross of Sunset for both pre-renewal and renewal (#111)
Direction fixes
- Updated the config setting attack_direction_change from 15 to 0 (official value); that means that a unit's direction will no longer change when it attacks; knock-back effects from e.g. Firewall will depend on the last direction the target walked into instead (bugreport:1322)
- Ensured that the default direction of a monster is always "north", so that immobile monsters will now always be knocked back to the south by e.g. Firewall on default settings, unless a skill like e.g. Backstab changes their direction (bugreport:1322)
Just a follow up of a0bd016.

(Seems something changed with the file attribute or what is it, changed a whole file lines and always be assumed unstaged files/uncommited changes)

1st Transcendent Spirit, monster position lag fixes
- 1st Transcendent Spirit will now work as on official servers (#116)
  * The max total stat that is granted by the skill is now BaseLevel-10 with a maximum of 50 instead of always 50
  * It will now work as Marionette Control and calculate the bonus at cast time rather than overwrite all existing bonuses
  * Agi Up and Blessing will now cancel the soul link
- Fixed various problems that caused position lags on the client (#118)
  * Added a define ACTIVEPATHSEARCH in mob.c; if active (default and official), monsters will only grab targets if the walk path to the target is shorter or equal their search range; search range depends on whether the monster is moving or not (range2 for standing monsters and range3 for walking monsters); this requires a lot of CPU load, if it causes trouble, just comment the define for old behavior
  * Fixed a bug that made monsters display "irregular movement with position lag" continuously when a status change ended that changed their walk speed
  * OFFICIAL_WALKPATH now also applies to monsters
  * If the path search fails while a unit is already moving, we will now issue of fixpos packet so that the unit does not only stop moving on the server, but also on the client
Expand 'checkvending' script
* Added returned values for buying store.
* Made returned values as bitmask. &1 - Vending, &2 - Autotrading, &4 - Buyingstore
