Added other docs sections to sphinx build

Added the "easier" docs to sphinx, which include the faq, cookbook, and
the tutorial.  The tutorial isn't complete.  NOTE: This work is all done
in the sphinx main directory. When it is good enough, you need to copy
the files to the 'documentation/sphinx' directory (for now).

Later, I'll adjust it to make Sphinx the main directory as well as,
perhaps, change the build directory _build to their actual destination
(ie 'documentation') if that's possible.
Tutorial images and registration_system demo added

Added remaining images to the tutorial section.  I also cleaned some of
them up as their right side had the remains of another window.

I added a couple of questions that I thought about to the FAQ.

I added the registration_system code to the cookbook page, which seemed
approprate.

Note in the checkin, but I downloaded the existing website from the
sourceforge location.
Added support and links page and registration demo

Added a couple of docs pages.
Added the easygui_demo_registration_app file to the sphinx documentation
_static directory.
