* clutter/clutter-model.[ch]: Allow unsorting the model (passing
-1 as the sorting column)
(clutter_model_iter_get_valist): Do not initialise twice che
return value.
* clutter/clutter-model.h:
* clutter/clutter-model.c:
(clutter_model_append_value),
(clutter_model_prepend_value),
(clutter_model_insert_value): Add a _value() variant for the
insertion methods, for use of the language bindings.
(clutter_model_append),
(clutter_model_prepend),
(clutter_model_insert): Do not return a boolean: insertion should
never fail unless for a programming error, in which case we have
plenty of warnings.

functions for ClutterModel: clutter_model_new() now takes a list
of GType/string pairs for both the column type and the column name.
(clutter_model_set_n_columns),
(clutter_model_set_names),
(clutter_model_set_types): Subclasses of ClutterModel will be able
to call clutter_model_set_types() and clutter_model_set_names() in
any order, provided that they don't call each function more than
once.
* tests/test-model.c: Update the test case.
Add more introspection capabilities to the base model class

(_model_get_column_type): Add API for getting each column's name
and the default implementation for ClutterModel.
(clutter_model_get_column_type),
(_model_get_iter_at_row): Add API for getting each column's type
and the default implementation for ClutterModel.
