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.

Generated map is now the default map in the mapconfig widget.
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:
