Documentation page updated

A few months ago, I had moved the FAQ stuff to the top of the
Documentation page because I was feeling it was getting lost down there,
and I figured it was referenced quite often.

I have reconsidered that and have moved it back down. Seeing that
the documentation section has been trimmed, the new ordering looks
perfect.
