I think this code is relatively stable now.  The new saved settings file
is "/etc/setup/setup.rc".  The settings are stored as:

key1
	setting
	...
key2
	setting
	...

etc.

One setting is "chooser_window_settings".  This is the field which
remembers what you last did with the package selection screen.  If you
have de-maximized it, that will be remembered.

Please let me know (via cygwin-apps of course) if there are problems
with this code.  It's a pretty big rewrite so I could have easily gotten
something wrong.
