I've added R_font_list().

This currently returns the list of fonts from the freetypecap file;
I'm not sure whether to extend it to include the stroke fonts, or
whether those will get added to freetypecap file soon.

I've also changed "d.font -l" to use this function, so we don't have
to re-write multiple freetypecap parsers if the format changes.

Future enhancement: add an option to return complete information
rather than just the name (e.g. "d.font -L"). But I'll leave that
until things have settled down a bit.
