Show LibreOffice controls in Glade's tool palette

Glade didn't show any LibreOffice controls in its tool palette
because the catalog didn't have any glade-widget-group element.
This adds a XSLT script to automatically generate such element.

A better version of the script would create separate groups for
each module/namespace, but currently I have no idea how to do
this with libxslt, as it doesn't provide fn::distinct-values().
