I don't like this.  Why should FreeType discriminate Apple Unicode
cmaps?  It's not FreeType's fault that there are buggy font editors
and careless font developers who don't check the correctness of its
products.

Anyway, I've fixed it differently in the CVS: There's now a loop for
searching a UCS-2 charmap similar to the loop for UCS-4; a (3,1)
charmap is now favoured over an Apple one.

Please test.
