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.

Fixes #1357

Returns select turfs with direction values not supported by their icons to default (SOUTH)
- Added a "Show Crew Monitoring Console" Verb to the AI Commands section of the AI's verbs.
Added some lines that accidentally'd when I used the file.
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.

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.
Resets weapons.dmi and tgstation.dme, meaning that the only diffs are to the code .dms (and those changes should be correct).  Next commit will handle adding the icons back to the synced .dmis.
-Petethegoat is love. Petethegoat is life. Made the procs global, so both the physical computer and the AI use the same proc.
- fixed ais being able to use computer when it was powered down
Used Aranclanos's code for combining swords without dropping both hands!  Re-added the icons to the fresh DMIs.  Self-testing found no issues, this is ready for someone to approve.
Removed optional use of .src for Aranclanos
It's now hacking via multitool instead of emagging via emag... maybe people will actually do this (:
Fixes dir for all "cafeteria" and "barber" floor turfs in the .dmm
