[clutter] text: Implement Scriptable interface for font-description

    text: Implement Scriptable interface for font-description
    
    This makes ClutterText implement the Scriptable interface so that we can
    have a custom property parser and setter for the font-description
    property. This works by simply passing the string description through
    to clutter_text_set_font_name.
