Moved surgery from WIP to modules, since it's not really that WIP anymore.
Split one huge file into several smaller ones for readability.
Removed the 'AnyColor' paint can from the spacebattle map, as the item definition was commented out.
Updated the labcoat object path to work with it's new definition.
Added back in the game/code/objects/structures/signs.dm , which was unchecked for some reason. Was causing an away mission to not load properly.
Added doublecheck for disfigurement
Moved germ transferring and blood splatters in parent 'begin_step' of surgery steps.

Merge pull request #2181 from caelaislinn/bleeding-edge-freeze

Supply pack tweaks, random event (system news announced at newscaster), cleanup
Fixed autopsy scanner defines.
Committing map changes for faux.
Proper fix for the projectile runtime.

Adds projectile autopsy messages back. Partial fix to issue #2153
required_players_secret added, which is the number of players needed for a game mode to start when that mode has been chosen at random.

required_players for most modes reduced to the number of antagonists + 1, as the variable is only used when the game mode is explicitly voted for.
More fixes to autopsy scanner, issue #2153

- Scanner will now print data even when only time of death is available.
- Scanner will reset chemtraces on new patient.
More fixes for issue #2153
