plugin otr: various improvments:
- messageSend trigger now use pre_xml_treatments so it doesn't block other triggers of higher priority
- text commands now use a very high priority, as it is local command and should not be blocked in most of cases
- new otrState signal, to send state change to frontends
- history is not skipped anymore, a future option may change this behaviour
- OTR trigger are skipped on groupchat messages
- context_manager is now in client instead of being global to plugin
- removed fixPotr as it is fixed upstream
note triggers should be improved for encryption methods, as skipping an encrypter may break security, but putting it in top priority may break nice features.
