[tex-live] [TL 2013 pretest] Win32's fc-cache doesn't read the variable `FC_CACHEDIR` and `FONTCONFIG_PATH` in texmf.cnf file

[Akira Kakuto]

Dear Qing Lee,

>     FONTCONFIG_PATH = $TEXMFVAR/fonts/conf
>     FC_CACHEDIR     = $TEXMFVAR/xetex-cache

Sorry for the change.  FONTCONFIG_PATH and FC_CACHEDIR are not used
in TL 2013.  They are fixed as
$TEXMFSYSVAR/fonts/conf
$TEXMFSYSVAR/fonts/cache

I'll recover them, if they are convenient,  in the next year: TL 2014.
I completely forgot to inform the change.

Best regards,
Akira KAKUTO
