Bugs don't kill chip

[BabyMaybe]

Bugs should kill chip on collision, but detect him as a normal block and avoid him. Probably need to add hit var and check for block identities. If chip runs into them they work fine, so messaging is working properly.

Fixed although infinite loop possible with solution if bug is ever surrounded on all sides by blocks. Should be a simple fix though and unlikely to occur during gameplay.
