plugin XEP-0045: various fixes/improvments: - use self.txt_cmds instead of self.host.plugins["XEP-0045"] - nick and options in join have now default values - directly raise ConflictError when room is already joined instead of using defer.fail - removed self.host.getClient where it's now useless because client is used instead of profile

# FIXME: remove this when RSM and MAM are in wokkel
# XXX: the Monkey Patch is here and not in src/__init__ to avoir issues with pyjamas compilation
