Removed a spawn() from the Destroy() proc of falsewalls.
Removed the falserwall type, now reinforced walls are a subtype of falsewalls.
Due to that, removed a bunch of copypasted code.
Falsewalls now spawn closed.
Falsewalls open/close timers are now proper, regarding their animation times.
You can't use a screwdriver on falsewalls while they aren't on a floor. (excluding shuttle floors)

Plasma falsewalls will now ignite.
Added a feedback message when you don't have enough sheets to create a falsewall.
Admin logs for igniting plasma walls, falsewalls, doors and airlocks.
Stadarized mineral_doors.dm.
Fixed the feedback messages for when you try to make a false wall with insufficient sheets.
Merged the open/close close from false walls walls and reinforced false walls into one.
