- Added 4 new HUD styles
- Humans recreate their hud if they change their UI pref mid-game
- Refactored how objects are added to the client screen
- HUD's are now handled by subtype and mob/proc/create_mob_hud()
- HUD visibility is no longer chained directly to the F12 button, it's a proc on HUD datums now
- Mobs only create/destroy their HUD when necessary, not every Login()
- Destroyed aim-mode, it didn't work and I couldn't make it work.
- Renamed all of the screen1_x.dmi files to screen_x.dmi
- Removed screen1.dmi, screen_gen.dmi now handles generic icons.
