Reworked the Belt Observer

- Belt observers now have four modes with different useful behaviours #83
- Fixed belt actors not syncing when items are not held in place but replaced
- Upward facing deployers can now act as item displays
- Fixed deployer fake players persisting after disassembling a portable contraption
- Creepers no longer take revenge on Deployers by default
