fonts/junicode: update to 1.002.

Junicode version 1.000 fully implements the Medieval Unicode Font
Initiative version 4.0. It includes numerous bug fixes, most
notably one that affected the stacking of diacritical marks and
another that caused glyphs to "explode" in certain printers.

The Greek face has been moved into its own font, Foulis Greek.

Junicode 1.001 adds some anchors at a users' request. Version 1.002
adds an anchor and a couple of glyphs requested by users and fixes
several bugs.
