2 changes fix to catacurse from lazy cat.
Added the 'fd_rubble' field
Rubble field will be generated in the vicinity of a cavein
Merge branch 'master' of https://github.com/TheDarklingWolf/Cataclysm-DDA into cavein
Added 'Crushed' disease to handle effect of cave-ins on player
Added map::field_effect() as a means of applying effects to things directly via fields
Added field_effect to roof cave-ins
Added 'DI_CRUSHED' disease to apply player effect for cave-ins. Currently not active. See map::field_effect.
Removed DI_CRUSHED disease implementation for now since it was being difficult. Replaced it with a simpler implementation. Made monster damage application more robust, including handling monster death if applicable. NPCs now take damage if caught in a cave-in. Vehicles do not.
