Huge commit to:

* Break stanza routing (to be restored in a future commit)
* Remove the old stanza_dispatcher code, which was never going to be maintainable nor extendable :)
* Bring us plugins, starting with mod_legacyauth and mod_roster
* Sessions are now created/destroyed using a standard sessionmanager interface
