Minor housecleaning. sw no longer spits out diagnostic output, comments

are now sane and match current code, I moved things around in GL so they
more closely match the sw code, as the sw code makes more sense now that
I *finally* understand what in gods name I was doing wrong. ;)

I also made minor changes to the help to indicate the minimum values of
the variables (sw can deal with 1, gl 0) as well as that you really
ought to use r_particles 0 instead of a setting of cl_max_particles 0 in
GL :P

Thanks for all the help taniwha, those last two bugs were kicking my
butt.
