    Added custom shortcuts support to launch scripts
    
    The problem is that Nautilus doesn't permit to map shortcuts to launch
    the scripts in the scripts folder.
    
    I added a function to read from a configuration file the shortcuts to
    map the scripts.
    When the scripts are added to the context menu they will have associated
    the shortcuts written in the config file.
