Personal eventing protocol (XEP 0163) support
I would like to see http://www.xmpp.org/extensions/xep-0163.html (XEP-0163: Personal Eventing via Pubsub) support in Gajim. SVN Psi already has it and it is a really nice feature. I could even implement it (along with other related XEPs, like User Mood, User Tune, ...) if only some developer show me how (like, where to find "hooks" in the Gajim source code to hack upon). PEP gives a lot of possibilities, so why shouldn't Gajim have it?
