Adds WJohnston's rainbow esword and dual-esword sprites.  Also corrected a few bugs involving esword sprites, mainly involving the player sprite not updating when they construct dual-eswords.  It turns out that player-sprite updating is magnets, so the eventual solution was for the player to drop both swords before they're deleted.  Since dual-eswords were already created on the ground, this changes very little.
A dual-esword inherits the emagged state of the esword being attack_by'd.
WJohnston updated the sprites with a 50% longer timing.
Finally finished adding double-toy-swords, emagged double-toy-swords, and improved some of the earlier fixes.  Swords no longer have to be turned off before emagging, the player-sprite overlay will update correctly now.

Extra charges can now be used to reduce the cool down of a wizard's spells. This effect can stack to different levels depending on the spell.
Reworked the equation so that you gain a constant cooldown reduction per rank
Additionally all spells can now use all 5 spell points now (though the functionality to have spells that don't follow this rule is still there).
The new variable "cooldown_min" defines (in deciseconds) what the cooldown should be if all 5 spell points are used on it.
For example if you had a 100 charge_max and a 60 cooldown_min, every rank used on that spell would reduce charge_max by 10
Specifics of how the cooldown is affected for each spell has been commented in
Gingerly nerfs the cooldown reduction on flesh to stone and magic missile
Fixes #1357

Returns select turfs with direction values not supported by their icons to default (SOUTH)

Request consoles print slips when a request comes in.
Finishes and enables "Extreme Priority" alerts through hacking, which cause the slip to be (harmlessly) launched at a nearby target.
Most recent messages are now at the top, so much less scrolling necessary.
Centralizes the request console's icon_state code.
Also adds me to the admins.txt because I'm tired of stashing changes to it.
- Anti-Copypasta update. You can also now type "crew" to get to the menu quickly.
Anomaly Neutralization

Anomalies can now be scanned to determine their frequency, and neutralized by sending a signal on that frequency.

By Pete's request, removes all the unnecessary calls to the byond "text" proc (which turned out to be all calls to the byond "text" proc, in this file at least.

Should bring admins.txt in line with tgstation upstream, and the icon files match the upstream ones too.  The icon files do still need to be edited, of course.
