Launcher: several fixes and improvements

- Reload map list each time the combo box is opened (needs to refresh if user installed a new map while launcher is still open).
- Reload playlists each time the combo box is opened (makes sure that the list is up-to-date if user modified it in any way).
- Use global VPK dir regex to parse out map names.
