template: gidx methods improvment: gidx methods now use the filtered name to return global indexes. For instance, if "widget" is filtered name, first index will be "widget", then "widget_1", "widget_2" and so one. If an other name is used, it restart (e.g. for "label": "label", "label_1", "label_2", etc.).

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
