    Don't return immediately in swfdec_loader_target_parse if the loader is in error
    
    Also update the hack for native FLV loading to call swfdec_loader_target_parse
    when the loader changed instead of just cninuing. This allows different parse
    functions in different targets.

    change the way swfdec_loader_load works.
    
    swfdec_loader_load now always returns a loader. If there was an error creating
    the loader, the loader will have been put in the error state on creation.
