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

	requires	"util.datamanager"
	module		"rostermanager"
	
function log(type, message)

function getroster(username, host)
