Doc: Move some remaining files over for modularization.
The files in this change were still in qtbase/doc/src or required for it. qtbase/doc/src should now only contain example documentation and images for the example documentation. Change-Id: Ia7ca8e7fd2b316e77c706a08df71303bc8294213 Reviewed-by: Marius Storm-Olsen <marius.storm-olsen@nokia.com>
