update to 13.2.0 beta 2
use the domain as the XMPP serviceName
remove jabber.ccc.de as an inband reg option
we don't support captchas yet :(
support custom ringtone selection
error message is injected at lower level; don't be redundant!
in some cases, connection can disconnet before login is attempted
Merge pull request #501 from n8fr8/master

XMPP fixes and ringtone selection fun!
