D81 writer plugin V0.1

Important:

This is version 0.1, lacking IEC mode and all error detection. Make sure
your C64 has burst mod (*1) and that you have disk in 1581 before
pressing RETURN. Verify errors hang C64 and 1581, and you need to reset
both to continue. Plugin also sometimes hangs when it should start
writing, forcing you to reset too. BAM copy isn't implemented either.


Now the lighter side:

D81 plugin is the fastest method to write D81 images to disk on C64.
Without format/verify that takes only 64 seconds. If disk needs to be
formatted, D81 writer beats OmniFlop (*2) too as it requires separate
format pass.

When started, program checks devices 8-11 to find 1581. If one is found
it then checks for burst mod. After that you are given a couple of
options:

8,9,0,1		select device 8-11 (only changed if new device is 1581)
F		toggle format
V		toggle verify
B		toggle BAM copy (if selected, only necessary tracks get
		written to disk. !! not implemented yet !!)

You will be given time estimation according to current options. Plain
write takes 64 seconds with burst mode, format and verify add 32 seconds
each.
