Doc: Updated url variable in qdocconf files.

In 5.2, the HTML output is in a flatter structure and when they are
hosted in qt-project.org/doc, the documentation will be found at
http://qt-project.org/doc/qt-$QT_VER



The url variable is used by projects outside of Qt 5 which need
to link to Qt 5 documentation, such as Qt Creator.
