* clutter/clutter-actor.c:
	(clutter_actor_set_property),
	(clutter_actor_get_property),
	(clutter_actor_class_init): Add the rotation-* properties,
	controlling the rotation angle and center on each axis. (#614)

	(parse_rotation_array), (parse_rotation),
	(clutter_actor_parse_custom_node),
	(clutter_actor_set_custom_property),
	(clutter_scriptable_iface_init): Add a new "rotation" custom
	property for expressing the rotation along each axis in a
	compact way:

	  "rotation" : [
	    { "x-axis" : [ <angle>, [ <y>, <z> ] ] },
	    { "y-axis" : [ <angle>, [ <x>, <z> ] ] },
	    { "z-axis" : [ <angle>, [ <x>, <y> ] ] }
	  ]

	(clutter_geometry_get_type),(clutter_vertex_get_type),
	(clutter_actor_box_get_type): Use the I_() macro instead of
	directly calling g_intern_static_string().
	
	* clutter/clutter-entry.c (clutter_entry_request_coords):
	* clutter/clutter-label.c (clutter_label_ensure_layout),
	(clutter_label_request_coords): Use CLUTTER_UNITS_FROM_DEVICE()
	instead of CLUTTER_UNITS_FROM_INT(), as "device" means "pixels".

	* clutter/clutter-private.h: Add the I_() macro for intern
	static strings.

	* tests/test-script.json: Test the newly added "rotation"
	custom property.
