I've been planning on adding a "row_activated" signal for a while, but
haven't done so as I've been trying to get the keyboard stuff under

It's even more complicated then that, as you need to consider cells like
toggle buttons that can be activated on their own (see
tests/testtreefocus.c as an example of such an application).  Anyway,
I'll add the button click case here in the short term so you can start
using it, and we can add the keyboard activation later.
