Start new Bonjour protocol plugin
2 months ago, Elliott Sales de Andrade

Start new Bonjour protocol plugin
This is mostly copied from the new XMPP protocol plugin, with icons copied from
the existing Bonjour plugin.
The id has a `-nouveau` suffix so that it won't conflict with the existing one.
Testing Done:
Ran `ninja turtles`; checked that an account with the new protocol could be added, though it doesn't do anything.
