[PATCH] add 'ualz' to MC extfs.

[SungHyun Nam <goweol gmail com>]

Hello,

I added 'ualz' extfs script.
I tested this patch with unalz-0.50.

You can get unalz:
    wget http://www.kipple.pe.kr/win/unalz/unalz-0.50.tgz

Below is the description of Debian unalz package:
    The utility used for decompressing alzip format file. unalz
    tool is the utility used for decompressing alzip format file.
    It mainly operates on files with names ending in '.alz'.

Regards,
namsh
