[WIP, Do not Merge] Mulebot lag fix

Work in progress for fixing the server crippling MULEbot lag.
Debug stuffs will be removed when all cases of lag spikes are
successfully replicated and removed.

Please comment your methods of replicating this bug, and I will work to
patch it.
Infinite loop fix!

- Fixes an infinite loop that was causing the worst of the server
crushing lag. MULEs not set to return home will properly process their
loading/unloading procedure if instructed to proceed to a location it
currently occupied.

- Removed the debug bits.
