    Bug 784502 - Multiple identical path entries for resources cause...
    
    ...resources to be loaded and shown multiple times
    
    Change gimp_path_parse() to filter out duplicate paths. This is the
    function at the bottom which is used by everything else, so should
    generically catch all duplicates.
