Change Disposal to absolute pathing

Started trying to fix a reported bug, ended up removing all of the relative pathing in the disposals code. My eyes hurt

- Also removed ninja snowflake code. If you attack the disposal bin with your big energy sword of death, it's getting flushed. #REKT

Fixes #2303
As in it fucking doesn't, this shit isn't broken, but here, I just changed 2048 FUCKING LINES for your amusement. At least the relative pathing is gone
