Updated rules.mak and level1/coco1/bootfiles/makefile
Updated the rules.mak file to remove the format entire image related
to drivewire server disk images.
Updated level1/coco1/bootfiles/makefile to create 3 new bootfile images.
These images are stripped down to just the common files needed
for vovdg games on os9 level 1. These bootfiles are for becker, dw,
and arduino. Also corrected a duplicated dd descriptor when building
some bootfiles that had both floppy_40d, floppy_80d, RBDW, RBBECKER,
and RBARDUINO. Removed the dd descriptor from each of these sections
and made it where the dd descriptor for the specific section was added
in the main bootfile list.
