plugin XEP-0060: MAM integration: - removed useless XEP-0059 recommendation - added XEP-0313 as a recommended plugin - parseExtra now manage mam_* keys (mam_filter_[name] to use a filter) - if a mam request is in 'mam' key of extra parameted in getItems, a MAM request is done, but the result is returned in the same way as for normal getItems, making like more easy for other plugins and for frontends

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
