Fix WebSocketClientConnector not sending the send buffer queued up
between starting the connection and the master server sending the ready
signal for it.
Implement notification to plugins for disconnect request, connect, drop,
and close. This allows plugins to properly handle slaves and the master
server shutting down without sending messages that will get lost.
Fix missing module declarations, broken lings, broken formating and
incorrect scopes in the documentation. For modules split over several
files it appears the only viable option is to use the memberof directive
on each documented member and only declare the index file as a module.
Send a mapping of the plugins the master server has loaded to slaves
vice versa. Limit the plugins that may be loaded by instances to only
those that the master server has loaded.
Replace socket.io with plain WebSocket using the ws library as it
doesn't really provide any useful tools over plain WebSocket when it
comes to implementing reliable communication that works across
reconnects. The widespread browser support for WebSocket also means
it has little value to add for the web interface over WebSocket.
Remove connection and client subclasses of Link and put the connection
logic into a "connector" class. The connector deals with sending
and receiving messages, handling the connection and reconnection of lost
connections and giving sequence numbers to messages.
This move the logic of the actual connection away from the link
sub-classes, which in turn means the connection should be a lot easier
to mock in tests.
