Added a sprite for welded vents. (Original courtesy of Cheridan) Added an overlay for connected canisters. (Thanks to ruarai) Updated one of the AI statuses to be animated. Fixed the original style hotkeys. git-svn-id: http://tgstation13.googlecode.com/svn/trunk@2409 316c924e-a436-60f5-8080-3fe189b3f50e
