git ssb

partially fixed by 441a05aed4f9aad688bbfcaa5da1a66b3282ab6f

running git-ssb against my proto-go-sbot now gives the expected output:

cryptnix% ./bin/git-ssb web
Listening on http://localhost:7718/
vote { name: 'Error', message: 'no such command: links', stack: '' }
{ name: 'Error',
  message: 'no such command: messagesByType',
  stack: '' }
{ name: 'Error',
  message: 'no such command: messagesByType',
  stack: '' }
{ name: 'Error', message: 'no such command: links', stack: '' }
no stream for incoming msg { req: -2,
  stream: true,
  end: true,
  value: true,
  length: 4,
  type: 2 }
{ name: 'Error',
  message: 'unknown command: gossip.ping',
  stack: '' }
sbot client connection closed. aborting

although I'm not sure which is req:-2 ... hmmm not closing this yet
