[Qt-creator] build qt-creator using qbs

[Jochen Becher]

Hi,

After long time I plan to add some new features to the modeling tool.
Adding new files I wondered if qbs can still be used to build Qt
Creator. But loading the qtcreator.qbs gives me hundreds of error
messages (using Qt Creator 4.3.1) - it looks like the qbs files were
never updated for changes from newer qbs versions.

Is qtcreator.qbs dead? In that case I would not update the modeling qbs
files as well.

Regards, Jochen
