fontforge requirement

[Graham Percival]

Since
  Issue 963:     check dependency versions for 2.14
  http://code.google.com/p/lilypond/issues/detail?id=963
is closed, I am extremely reluctant to bump requirements now.
According to configure.in,
STEPMAKE_PATH_PROG(FONTFORGE, fontforge, REQUIRED, 20050624)

Jan, are you hoping to merge Woff fonts before 2.14 ?  if so, we have
a problem.  Since it needs to be so new ( 20100501 ), I would really
like to postpone that until 2.15.  (unless it can be added in such a
way that normal lilypond usage is fine with 20050624... I'm not
certain what the woff stuff is; I'm just anticipating a potential
problem).

Cheers,
- Graham
