Checkpoint: working matterbridge server

I was able to make matterbridge work, but only to realize that it doesn't
support private groups on most services. So I can't use this as a replacement
for other chat systems as I desired.

I ended up using my conversations.im account due to the lack of MUC support in
my current server.

I was also able to setup the Converse client, but my Prosody server also doesn't
have HTTP (or WebSockets, I don't remember) yet, so it didn't work for my
server.

So this may serve as a useful future reference, but I pan to turn off the
matterbridge server itself.
