Add Jabber plugin (alpha version, many Jabber features are missing)

This commit introduces Jabber/XMPP protocol for WeeChat. It uses iksemel lib.
Please note many major Jabber features are missing:
- roster management (add/remove/.. buddies),
- MUC,
- transports.
It is possible to define servers (with /jabber), connect to them (with
/jconnect), disconnect (/jdisconnect) and chat with buddies (with /jchat).
