Handbook conversion done

I finished vetting for 5.x references and hardcoded 'FreeBSD'.  The handbook
should be at least mostly OK for use now with DragonFly.  I'd appreciate if
people could give a section or two (I don't expect anyone to read all
50,000+ lines) a look-over and note any obvious inaccurate statements. 

Assuming there's no big problems found, I'll commit this.

If anyone's looking to do documentation, we need a writeup of the install
process using the curses and cgi front ends.  Someone testing the Linux
compatibity with MatLab or some of the other apps would be good, as would
looking at Advanced Networking.
