CVS tags handbook patch

[Dave Hayes <dave@xxxxxxxxxxx>]

Attached is a brief patch to the handbook to explain the purpose of
HEAD and Preview. I also sorted the list of tags, in my mind this
makes more sense.

This is attached sans MIME, I dont know how you guys filter MIME
yet. Old school is in effect. :)

I put this into "docs" and not "submit" based on a sense I got in a
private email that it would be wise to discuss what goes into "submit"
before it goes there. 

I'm sure someone will enlighten me ast to what mistakes I have made.

I was to learn later in life that we tend to meet any new
situation by reorganizing; and a wonderful method it can be
for creating the illusion of progress while producing
confusion, inefficiency, and demoralization."
