Allow localizations to change the text direction

Browse Source 
The locale translators of Clutter are also the ones that should set
the default direction of the text in a Clutter user interface.

This commit adds a translatable string that defines the direction
of the text; the translation authors will change it to the correct
value and that will determine the default direction.

The default text direction can be overridden by using the
CLUTTER_TEXT_DIRECTION environment variable, or by using the
--clutter-text-direction command line switch. In any other case,
the locale will determine the text direction, as it should.
