Update the list of authors to put Vadim Zeitlin forward and add Stefan Csomor.

Put myself (VZ) forward at Robert's expense and also add Stefan to a couple of
places where he wasn't listed at all.

Update the date in the manual for 3.0 release.

Use 2013-11-11 as the release date as we're -- gasp -- close to actually
making it.

Emphasize the importance of reading the changes section.

Mention that the changes since 2.8 could be useful to read even when not
actually upgrading since 2.8.

Change the titles of some pages for better appearance on the main page.

Try to make the titles of the pages linked from the main page of the manual
more clear and consistent.

Rewrite the introduction page of the manual and update its main page.

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.
