doc reorg complete

[Graham Percival]

I've finished the major doc reorganization I had planned for last 
month.  The changes are in CVS, and on the web at
http://percival-music.ca/Documentation/user/lilypond/index.html

If I've asked to wait for a few days until I've finished, go ahead and 
do doc stuff now.  :)

My plan is to sort out the Bug Meister stuff, and then look at adding 
the two-pass spacing stuff from the NEWS, unless Cameron really wants 
to do that one.  Of course I'll still respond to issues with the docs 
when they arrive, but I don't plan on writing anything major for the 
next few weeks.
