General updates to the documentation for people I forgot to include in
previous releases. Also added websites where applicable.
Update AboutDialog to be more current, showing only those members
currently active in the Stella project and the other teams that have
contributed code. For more specifics, you should now see the manual.
Basically consolidated all contribution info into one document, so it
has to be kept up-to-date in only one place.
