plugin ip, params: plugin IP discovery, first draft: - a dedicated plugin now manage IP discovery, for now it uses external website, but it should implement XEP-0279 soon - a permission is requested to user for calling an external website. Once the permission is granted (it's global), it is not asked anymore. - the ip is discovered on demand, and cache is kept for the session. - memory.params.getParamA has a new parameter use_default, which allow to get None when a parameter is not set, instead of the default value. This allow to detected when we need to do the first permission request. memory.getParamA don't have this parameter.

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
