From Luis Ontanon:
- moves mate configuration from proto_register to proto_register_handoff
- add the config file protocol preference
- every item (gop,gog,pdu) has it's own ett
- the tap doesn't do nothing, it just primes the tree
- analyze_frame() what once was the tap now is called by the dissector
- should work with tethereal now (to be tested)
