File restructuring!

This brings down a bunch of defines from /code/defines/obj.dm unto their appropriate files.

I've moved morgue.dm from game/machinery into game/objects/structures since that file contains no machines.

I've reorganized the objects/items/stacks folder and made a 'sheets' and 'tiles' folder to keep things separate

I've separated stool_chair_bed.dm into its own folder which now contains the files: stools.dm, chairs.dm, bed.dm and alien_nests.dm to make it a little easier to go through.
