Added action functions to reconnect.  Get windows with get_whndl, interact
with a pycwnd made with make_pycwnd, click with pycwnd_click, send strings
with pycwnd_string, change a whnd to it title text with whnds_to_text, and
restart_game, to combine it all to attempt a reconnect and reopen the
game.
Add defines for bnet coords to help reconnect. Add a copy of c() to
convert scales.
Add ability to restart the client.
Small corrections.  Use 'global' lower and upper green scalars.
