Resync actual binaries, admin/programs.txt, and man/man7/gromacs.7
Between tools acquiring g_ prefixes, new binaries being introduced, and a few more dropping out, the list in programs.txt, gromacs(7), and the actual files shipped have all drifted slightly apart. The attached patch resynchronizes all of them. (g_luck, g_logo, demux.pl, and xplor2gmx.pl are still not represented or documented.)
There's also a one-liner change to admin/mknroff.pl that replaces hyphens with dashes -- which only applies to the description of g_rmsdist.
