extfs: .cab and .ace

[G Jansman]

A long time ago I've created an ucab script to support .cab (and uimg for 
support of FAT disk images). They can still be found in the mail archive.

Since an improved cabextract version appeared I've improved the ucab script. 
Extracting files has become much faster. Both ucab versions don't support 
changing the archive (adding files etc.) or InstallShield .cab files.

Anyhow, here's the new ucab script. How to install the script can be found 
in my first mail and in $(mcdir)/extfs/README.

Anyhow, here's the ucab script:
#! /bin/sh
#
# Written by Guus Jansman
#
# This is a parser for Cabinet archives in Midnight Commander. You need
# the GPL cabextract program (version >= 1.0) written by Stuart Caie.

# Limitations:
# - Archives can only be viewed
# - Problems with empty directories as created by MsCab (non-standard cab 
files)
