Feature/s2s

After fighting with rebase and it rewriting my changes for no reason, I just went with making a new branch and pushed my changes there. It was for a site to server link protocol (and some GroupChat-related stuff) that would make interfacing with GroupChats on the Escargot site possible.

I was thinking of just copying my changes to the new version of the master branch, but it's too late for that, plus it would've been a pain from the start. I just want to finally push the changes and get it over with.
