makeflop.bat relies on DOS 5+ batch file abilities

[MobyGamer]

makeflop.bat was tested on DOS 3.1, and the branching (and echo statements for some reason) failed to work. See if there is a way to rewrite makeflop.bat such that it works in DOS 3.x.

Alternately, write an .exe helper program that calls the formatter+imager, but this shouldn't be necessary...
