Fix MSG_ReadDeltaKey setting bit 1<<bits often
MSG_ReadDeltaKey would often set 1<<bits, it should never be set. It exceeds the size of what was being read.
Worked okay for weapons/forward/right/up as they stored as chars (value would wrap around to correct value, lucky).
Angles had the wrong value, not sure if it was causing issues.
