This just adds some vars that the refactor will use. Putting this in a separate PR prevent the damage refactor PR from becoming too big (number of files changed) and hard to read and review.
Introduces the resistance_flags bitflag that replaces unacidable and burn_state.
Moves the armor var from item to /obj level and gives specific armor values to many objects, the armor list also gets two new armor types: fire and acid, which will be used in the refactor. the new fire and acid armor values are given to plenty of items.
Moves everything on a 15+ layer to a plane. So now you get screen catcher (-99, was already on a plane), lighting (15), effects that ignore lighting (16), fullscreen UI effects (18), screen objects used to build the UI (19), actual equipment in the UI slots (20), and everything else (0).
Also created a file to contain plane and layer defines for hopeful eventual use.
Hopefully this doesn't change anything now but does enable some nifty new features in the future.
closet.dm, costume.dm, decal.dm and window.dm have been knocked out of the define folder and their defines have been moved into appropriate files.
The closet folder has been re-organized a little.
supplypacks.dm has been moved into the datums folder since that's what it is.
