Updated swarm pet AI to be consistent with live.

*OLD AI: Swarm pet would lock on to target until target died, then depop as soon as target died.

*NEW AI: Swarm pet will attack cast on target, NOT perma locked it can change targets if attacked
by something else that generate more hate. When target dies swarm pet will follow owner, if owner is
attacked by something else the swarm pet will attack it (until duration timer despawns the pet).

Updated perl quest function: MakeTempPet(Tspell_id, name=nullptr, duration=0, target=nullptr, sticktarg=0)
Implemented perl quest function:  Mob::TypesTempPet(npctypesid, name=nullptr, duration=0, follow=0, target=nullptr, sticktarg=0)
Note: 'sticktarg' field will cause the swarm pet to use the OLD AI

Rule to use OLD AI only - default is disabled.
Optional SQL: utils/sql/git/optional/2014_11_15_SwarmPetTargetLock.sql
Implemented NPC Special Ability 41 'Allow To Tank', gives NPC opportunity to take aggro over a client in melee range.

i hate the change log
SUB EVENT CAST ON will now be parsed in player.pl
(note: exports $spell_id)
Fix for perl CastSpell function so it will use a spells innate resist diff
settings if no override value is put in the function.

Due to recent changes in
how we defined that variable it would set it to 0 resist diff by default
when called from perl.
Special Abilities column fix for older updates and newer database engines for the automatic database updater.
db_update.pl changes
Manifest update
Temp merchant items could duplicate slots also...
db_update.pl update
db_update_manifest.txt update
2014_09_20_ban_messages.sql fix for non PEQ account tables missing expansion column
SQL Source update fixes for newer DB versions
db_update.pl update
Implemented Automatic Database update and versioning system
Created database revision define, this is located in version.h in common #define CURRENT_BINARY_DATABASE_VERSION 9057
	- This revision define will need to be incremented each time a database update is made
	- Along with a revision define increment, you will need to update the db_update manifest located in:
		- https://raw.githubusercontent.com/EQEmu/Server/master/utils/sql/db_update_manifest.txt
		- An entry needs to be made at the bottom of the manifest, the entry is quite simple
		- Example: 9057|2014_11_13_spells_new_updates.sql|SHOW COLUMNS FROM `spells_new` LIKE 'disallow_sit'|empty|
			- This latest example is checking to see if the spells_new table contains the column 'disallow_sit', if its empty, the update needs to be ran
				- More examples of match types below:
		# Example: Version|Filename.sql|Query_to_Check_Condition_For_Needed_Update|match type|text to match
		#	0 = Database Version
		#	1 = Filename.sql
		#	2 = Query_to_Check_Condition_For_Needed_Update
		#	3 = Match Type - If condition from match type to Value 4 is true, update will flag for needing to be ran
		#		contains = If query results contains text from 4th value
		#		match = If query results matches text from 4th value
		#		missing = If query result is missing text from 4th value
		#		empty = If the query results in no results
		#		not_empty = If the query is not empty
		#	4 = Text to match
	- The manifest contains all database updates 'Required' to be made to the schema, and it will contain a working backport all the way back to SVN -
		currently it is tested and backported through the beginning of our Github repo
	- On world bootup or standalone run of db_update.pl, users will be prompted with a simple menu that we will expand upon later:

Created db_update.pl, placed in utils/scripts folder, used for the automatic database update routine (Linux/Windows)
	- db_update.pl script created db_version table if not created, if old one is present it will remove it
Created db_dumper.pl, placed in utils/scripts folder, used for the automatic database update routine backups and standalone backups (Linux/Windows)
World will now check the db_update.pl script on bootup, if the db_update.pl script is not present, it will fetch it remotely before running -
	when db_update.pl is done running, world will continue with bootup
world.exe db_version - will report database binary version
db_update.pl DB upgrade script - Linux Fixes
Turn off potential warning garbage for different versions of perl
Fix for invalid input error when script is ran from world during bootup.
