Fix two memory leaks in GTK frontend.

Browse Source 
- The file selector for loading and saving gets a g_free().
 - The handling of saving (menu_save_event) gets an sfree().
 - It's also slightly restructured to prevent future errors.
 - menu_load_event was already structured to prevent this error.
 - The OLD_FILESEL code seems to not need a g_free().
