* Sun Apr 14 2013 Martin Kolman - 0.40.3 - GTK GUI: pottentially faster automatic & batch tile download - and other activities, such as online lookups, that use threads - looks like gobject.init_threads() and gtk.init_threads() was not called before gtk.main() - as result, Python threads might have run only when some GTK events happened - this would explain why modRana sometimes downloaded tiles slower with blanked screen - QML GUI: new nested map laer selection dialog that shows all layers - it now shares the same data modeld with the GTK GUI - as a result, both GUI now should now show the same list of layers
