Hi!

This is a tiny patch which adds two signals to GtkEntry, "got_focus" and
"lost_focus". They have proven very useful to me, "lost_focus" at least,
because usually you don't need to call a signal handler on every little
"change" in the text, only after you're done typing.

Hope someone can put it to use somewhere...
