skeleton atari 400/800 floppy list. (1 entry)

Browse Source 
note, currently only supports .atr format due to image.filetype() not returning anything useful when softlist is used (thanks to micko for advice on various things)

(no credit wanted, this is just to address the 'where is jumpman' thing that was posted on MW and give a softlist entry for regtests on this code)

Atari 400 / 800 floppies
(skeleton list)
note: many 'original' floppy images are in .atx format, whereas cracked / unprotected ones are .atr format
.atx is unsupported, although apparently has been reverse engineered (insert info link here)
There are also images in .xex format?
