font-patcher: Add option to force patching in box drawing glyphs

Browse source 
[why]
When the original font designer's idea of cell height differs from the
height we deduce the box drawing glyphs come out with the wrong size (if
we do not touch them, for example because the font already has a
complete set).

[how]
Add option that enforces patch-in of the box set.
