done in cvs. (for GRASS_FONT only)

d.labels still won't respect d.font, but if the font changes there is no
way to know what it started as for the next font-less label, so I'm not
sure it would be a good idea to try / have it change the default font
part-way through.

GRASS_FT_FONT seems like the obvious choice for removal as it is now a
subset of GRASS_FONT, but not the other way around.
