upgrade to sifr font data

[nhummel]

I've been able to add glyphs that sifr can display to include a wider range.

Instead of [a-z], [A-Z], [0-9], and puctuation, + some other random glyphs.

We now have all of Latin-I, Latin Extended A, B and Latin Extended Additional, which is far as I can tell is a proper super set of what we had before.

The size has gone from 7.9k to 21k.

I'll be using this modifed sifr file for us, as we need some of the extra glyphs

Is having Latin-I useful to anyone else?
Would having other sets added be of value to other? (If we put everything in, the size is 158k)
