Tiny patch for gtkentry

[Vidar Madsen <vidar vidar prosalg no>]

Hello.

Recently I needed a GtkEntry which reacted to receiving and losing focus
(I got major(!) flickering when triggering on "changed"), so I put
together this tiny patch which introduces two new signals;  "got_focus"
and "lost_focus". I thought maybe somebody else might find this useful
too, so here it is...
