plugin text syntaxes: various improvments: - syntaxes and default_syntax are now class attribute instead of members of params_data - removed local exception UnknownSyntax in favor of exceptions.NotFound - syntaxes are now saved with a key which is name in lower case and stripped, unmodified name is put in syntax's data - new getSyntax (syntaxGet in bridge) method to get syntax key and raise an error if not found. Can be used by frontends to check that a syntax is known.

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
