[Devel] clean up in cidload.c

[山内 英敏]

Hello,

Here is a patch to remove is_alpha in cid/cidload.c.
It is obsoleted and we should use ps_parser_skip_alpha.

P.S.
My CID CMap support code already works. Two functions, Get_Char and
Next_Char, work with CMaps with usecmap operator. (e.g. Euc-v) But it
is not the time to post it because it is not clean yet.
