Website First WASM Steps Experience: Reformat demos/mandel.asm source code to fit to 80 columns

[sy2002]

When walking through the tutorial on http://qnice-fpga.com/emulator.html, it is part of the tutorial to look at the source code of demos/mandel.asm using shell and cat.

Since our VGA screen is 80x40, we need to make sure, that the mandel.asm source code fits to 80 columns, otherwise the first user experience of somebody starting to explore qnice using the above-mentioned tutorial is not good as can be seen here:

I assigned the task to myself, as multiple steps are necessary, to make the reformatted source then actually visible on http://qnice-fpga.com/emulator.html, including: making a new disk image and uploading it to our disk image repo.
