* clutter/Makefile.am: * clutter/clutter.h: * clutter/clutter-scriptable.[ch]: Add the ClutterScriptable interface; by implementing this interface, a class can override the UI definition parsing and transform complex data types into GObject properties, or allow custom properties. * clutter/clutter-script.c: * clutter/clutter-script-parser.c: * clutter/clutter-script-private.h: Rearrange the code and use the ClutterScriptable interface to parse and build the custom properties. This cleans up the code and also it makes it more reliable (the complex type parsing is now done using the target type and not just the name of the property).
