[DejaVu-fonts] patch old italic alphabet

[MaEr <mk....@we...>]

Hello!

I want to contribute these Old Italic glyphs to DejaVu Sans, regular, 
oblique, bold and bold-oblique (see attached patch file).

I have tested the glyphs with Open Office (see PDF file, the glyphs 
should be embedded).

Please let me know if the glyphs are usable and if you can include them 
in the four font files.

With kind regards
MaEr
