plugin PubSub Schema: schema helper methods: 3 new methods are introduced by this patch: - psSchemaUIGet to get XMLUI from node schema - psItemsFormGet to get items as XMLUI when we know they are data forms - psItemFormSend to set item from values when we know it's a node with schema. For this method, schema can be specified, and if it is not it will be retrieved from node (which imply an additional XMPP request)

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
