#108 One disk drive icon for every disk drive

[Marcos Cruz]

As already mentioned by other user as part of suggestion ticket #72, I suggest showing one disk drive icon for every disk drive, with its corresponding digit or letter identifier.

I usually work with more than one disk on G+DOS, TR-DOS an +3DOS, and many times I miss the information provided by the LED of a real disk drive, in order to know which drive is working, or even which drive has a problem and does not stop...
