Add old-style numerals

I've designed new versions of 0, 1, and 2 that fit within the
x-height.  6 and 8 don't change at all (and are unmapped).  The other
digits are all moved down by two pixels so their top edges are at the
x-height and their bottom edges at the descender height.

This is very simple (and much simpler than my previous attempts), but
seems to be satisfactory.
