Remove stray carons, fixes #3, line height

We had problems with excessive line-height in FontForge generated OTF’s. Big
thanks to Khaled Hosney: he pointed out in a discussion on fontforge-devel
that some of the characters had accents way above their normal positions. This
was causing the seemingly superfluous linespace.

The problem manifests itself in alternate versions of the Scaron, scaron,
Zcaron and zcaron glyphs. They were removed.
