[ft] Telugu support in auto-hinter and ttfautohint

[Werner LEMBERG]

Folks,


I've added Telugu support to both FreeType's auto-hinter and
ttfautohint.  To be more precise, blue zone support is now available,
which should give better alignments.

Please test the git repositories and report any issues – since I don't
have real knowledge of this script it's likely that there are still
issues.
