quick frontend, primitivus, wix: MUC private messages management

/!\ not fully finished, backend part is not done yet /!\
    - as resources are discarded to manage chat windows lists, a pretty dirty hack is done to work around this:
      full jid is escaped using a prefix (it becomes invalid and resource is preserved).
    - new quick_utils module, with helper methods. escapePrivate and unescapePrivate implementations
    - MUC private messages are not managed in Wix yet
