Add clutter-text properties to allow getting access to the underlying
ClutterText actor. This corresponds to the get_clutter_text() methods.
The PROP_LABEL and PROP_ENTRY enum values are renamed to PROP_TEXT to
match the names of the properties that they correspond to, and the
properties of NbtkEntry are reordered into alphabetical order.
Based on a patch from Colin Walters
