Bots keep data about themselves now in bot_t.
Fixed bug in test cases for protocol messages

With the new system, you can no longer create a bot_t on the stack.
 (i.e. bot_t._data must point to valid memory)
Fixed bugs in format_packet, decode_packet, free_packet. Many tests.
Merge branch 'fix_the_herp' of github.com:NosotrosNueces/mcc into fix_the_herp
All for you thony
