Cleanup behavior bitstream reads (#888)

Browse Source 
* Add failArmor server side

Address out of bounds reading in behavior

Address the basicAttackBehavior reading out of bounds memory and reading bits that didnt exist, which occasionally caused crashes and also caused the behavior to do undefined behavior due to the bad reads.

Tested that attacking a wall anywhere with a projectile now does not crash the game.  Tested with logs that the behavior correctly returned when there were no allocated bits or returned when other states were met.

Add back logs and add fail handle
