Can now change theme for static and mission maps. Fixed mission map descriptions that had commas which broke them. Now, you must escape commas in map descriptions. Made bgwidget repaint on animation tick to avoid buffer-not-clearing issue with widgets that change overtop the background leaving a ghost image of the widget's previous state. Generated map is now the default map in the mapconfig widget.
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:
