More on user doc

[GSR - FR <famrom infernal-iceberg com>]

Hi:

I added some sections, following the current style, so I do not lose
the info. OTOH, I have doubts about the current organization. It is a
big bulleted list, sometimes with high tech details (user can be
interested knowing why there is X11 or why that means there is a
special program named "window manager"... but exact versions seem to
be a waste of user attention) and others skipping information or
reasons for things to be (yeah, I know, incomplete). 

User doc should be about getting a primer into Sawfish basics so he
can look up more info later. Some kind presentation or small ref book
or small "how to use this new electric drill you got" (no, I do not
mean changing format, I mean the focus).
