Restore widget listeners in new project page

The widget listeners which update the wizard state when you change the
min sdk version, or the target sdk version, went missing in changeset
4ef523b33a392e6c9ca40, probably because a cut & paste operation of a
widget in WindowBuilder (to move it in the hierarchy) also sometimes
removes associated event handler code in other methods (!).

This CL restores this code.
