core, plugin XEP-0045, frontends: change frontend method "setStatusOnline" for "setPresenceStatus": - remove parameter "online" (can be guess from "presence" value) - process "statuses" dict in quick_frontend, so this method can get a simple unicode "status" - add C.PRESENCE_STATUSES_DEFAULT to define the key to use for fallback status

Use this module to temporary store files that need to be integrated to other
projects such as Wokkel.

For example, the changeset that introduced this folder adds RSM (XEP-0059)
support to Wokkel. The files in sat.tmp.wokkel are imported over the initial
wokkel files from sat.plugins.__init__.py
