Store the default font name inside ClutterBackend

Browse Source 
The default backend stores some of the global defaults, like the
font options, text resolution, double click settings. It should also
store the default font name, to allow various text-based actors to
share the same settings.

When the font name changes, the ::font-changed signal is emitted,
to allow actors to pick up the change.
