Removed two-player hacks from cannon and object packets

Browse source 
Increased error checking of get_behavior_from_id
Made failure logging for packet_object a lot better
Changed debug logging to show global index instead of "Server/Client"
Changed debug keyboard binds to support more keyboard types
Made SyncObject's rxEventId de-duplication per-player instead of one-player
Removed sizeof(enum) from packet_read/packet_write
