ObHack Windows zipfile fixed

I haven't used the program to make .zip files in *NIX in a while, and its command line parameters can be a bit confusing (the correct way to make a zipfile is zip -r ObHack-win-006.8.zip ObHack-win-006.8, with that '-r' being lower case; the manpage incorrectly states that you can do it as zip -r ObHack-win-006.8 ObHack-win-006.8 but that doesn't actually work); as a consequence, the zipfile had a single invisible file with the name .zip in it.

I have remade the zipfile and uploaded it to the ObHack webpage.
