All code that was at xfce4-14 has been moved to xfce/*.
Old expressions that aren't rewritten might be abandoned or broken.
Additonally I've ported the xfce4-14 thunar expression to support
thunarPlugins. We can now support this interface in the Xfce module
again, although I'm not sure if we have any plugins packaged that support
latest thunar.
- forgotten mousepad update, including some wrapping magic
- dealing with panel plugins (either fix or mark as broken)

- remove some libxfcegui4 occurrences, as it's being phased out
- minor stuff
