Get rid of 20 year old information (it isn't that impressive that we offer to
provide wxWidgets on a CD-ROM any more) and drastically compress the
introduction page while, hopefully, making it more readable and useful for
people new to wxWidgets.
Update the main page to provide a short documentation walk-through and to
organize the different links in order of their usefulness instead of whatever
was used before (random?).
Also add links to the alphabetical list of classes which is very useful but is
not immediately apparent in the Doxygen menus.
