Let me know if I missed an item or if you don't think an item should have the flag.
* Cleaned up a bit of the gun code.
* Fixed an issue with shotgun darts not working in barrel shotguns.
* Made the on_hit() have a zone, will be used for syringe guns in another PR.
* Removed the unused sleepy pen.
* Changed /obj/item/weapon/gun/projectile/shotgun/pump/sc_pump to /obj/item/weapon/gun/projectile/shotgun/sc_pump, there was no /pump/ anywhere else.
* Shotgun darts will follow the new flag.
* Shotgun darts are now open containers, and I removed the snowflake check for them in syringes.
* Added logging for reagents in any projectile.
Everything that had abstract var now has ABSTRACT flag
Everything that checked abstract var now checks ABSTRACT flag
Fixed some runtimes
Fixed click code and face direction changing while cuffed
Added del to all attack_* of the proboscis in case shit goes real
AStar is still weird so added a simple sanity check
Moves the constants from defines and compile_options files into the __DEFINES directory. The compile options in the latter file that are actually tweakable remain in their existing file in the code directory.
Constants from DEFINES.dm, globals.dm, names.dm, and global_lists.dm have been moved into the _globalvars subdirectory.
stylesheet.dm has been moved into the interface directory since that's a better place for it.
This move contains no code changes for stock TG. It is purely an organizational move meant to clean up hard to read code.
Some global constants that appear to be unused have been put into unused.dm, but not unticked. This list is by no means exhaustive.
Branches should be aware that they need to move any additional defines and global constants manually.
