Subject: [PATCH] Add releases/bin2dsk.sh

Shell script that uses StuffIt, Unar and ds2dsk to create a dsk from
Apple provided disk images.

Updated readme to remove dead links under floppy disk section and
provided a new link to Apples software on archive.org as the web page no
longer exists on the Apple website. Disk images are still available via
the Apple FTP but directly listing is disabled.

 Before loading a different disk image it's recommended to eject the previously inserted disk image from within MacOS.
 
-Some system floppy disk images in matching dsk format can be found at [here](http://www.rolli.ch/MacPlus/welcome.html). Some nice applicatons on 400k dsk images can be found [here](http://tkc8800.com/page/Macintosh-128k-512k-disk-images). Official system disk images are available from apple e.g. via [ftp](http://ftp.iinet.net.au/pub/apple/US/Macintosh/System/Older_System/System_6.0.x/). Under Linux these can be converted into the desired dsk format using [Linux stuffit](http://web.archive.org/web/20060205025441/http://www.stuffit.com/downloads/files/stuffit520.611linux-i386.tar.gz), unar and [dc2dsk](http://www.bigmessowires.com/dc2dsk.c) in that order.
