multi-tzx2sfs script

[stemsee]

I only discovered today that there is a rightclick menu option to convert a .tzx install package to sfs. I had developed a small script which did similar but it also downloads the packages and then creates one big sfs. So it is easy to create a Music or Art sfs with all your favourite packages. Also there are two types of post install package 1) install/doinst.sh and 2) /var/log/setup/setup.<package name>: ... the former is implemented the latter is not implemented here. It seemed to me that the /install/doinst.sh is a relative script, and works within the created directory file structure. I'm trying to improve the script in case there are any obvious incompatibilities.

but here it is
