plugin identity: plugin identity first draft: this new plugin is a high level way to manage profile or entity identities, i.e. informations about them. It has been created to handle easily data which can be in several location (e.g. roster, vcard-tmp, vcard4, etc.) For now, only nickname can be gotten/set (set only works for profile's own identity, while get can be used on any jid).

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
