Comment:

 Reopening, as the cellrenderers in activities list and Journal are still
 missing.

 The following patches add the mouse over feedback for them.  I have to
 figure out how to make the press feedback.

 Because cell renderers don't inherit GtkWidget anymore, the styling can't
 be done using the __gtype_name__ .  Instead, it has to be done adding a
 css class [1] to the style context, and rendering the background in the
 reimplementation of the do_render method.

 For reference, see how GtkCellRendererToggle is implements render [2] and
 how Baobab app does it [3].
