Joseph Poon 1981001a29 Started working on state machine
* Added description in lnwire/README.md for state machine
* Figured out mutex stuff...
* Started the State Machine (using dummy functions for net/db)
* Minor corrections in wire protocol (changed some names/types)
    - Renamed StagingID to HTLCKey of type HTLCKey (uint64)
