Subject: [PATCH] TextEditor: Show action long texts in the status bar :^)

We now display a description of the currently hovered action in the
text editor application's status bar. This is pretty cool! :^)

This is currentl achieved via the hooks on GUI::Application. Longer
term we'll probably want to find a more flexible abstraction for this,
since not all applications will be as simple as TextEditor.
