This commit adds some cursory documentation along wit minor field modifications to all messages which deal with adding HTLC’s, or updating remote commitment transactions. The messages for dual funding of channel is left purposefully undocumented as all initial negotiations will be single funder by default. A revamp of the testing infrastructure of lnwire will be committed in the near future.
