plugin XEP-0245: removed plugin XEP-0245:

at the end it adds complications to handle XEP-0245 in backend (because edge cases must be handled: info type with group chat, history when message is info but for a group chat, etc) while it's trivial to handle it in frontend.
    So /me detection is handled in QuickFrontend and cmd_me is back into plugin_misc_text_commands, it is the choice of the frontend to display or not the "/me" (for frontends based on QuickFrontend it remains automatic).
