Primitivus: better popups handling: - widget to remove can now be specified in removePopUp: if it is not the current one, it will be removed from queue - Primitivus.Alert method is a shortcut to display an Alert which will be removed on "OK" press - showDialog is now obsolete and removed, if generic dialog creation is needed, XMLUI can be used

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
