Three additional file formats

I thought there were enough disk versions of the game already, but I noticed someone was trying to make a +D version, so I made another Spectrum version for +D and also for Disciple, which also works with modified versions of these devices for Uni-DOS. The version of the game for this entire group of disk systems is in just one MGT disk image file, because it contains three operating systems on the same disk, so the game should automatically load and run just by the RUN command on Disciple, +D and their Uni-DOS versions.

While I was at it, I also made a Spectrum version for Didaktik 40 / 80 / Kompakt disk in a D80 file. I couldn't test it with all versions of MDOS and it was only tested in an emulator, so I hope it will work everywhere.

A little later I added a Spectrum version for the Wafadrive tape drive in a WDR file. I couldn't find any information about controlling Wafadrive from assembler, so the loader isn't exactly as I imagined it, but it seems to work without any problems (at least in emulation).
