CMakeLists: Define QT_USE_QSTRINGBUILDER for the Qt target
This is a compile definition introduced in Qt 4.8 for reducing the total potential number of strings created when performing string concatenation. This allows for less memory churn. This can be read about here: https://blog.qt.io/blog/2011/06/13/string-concatenation-with-qstringbuilder/ For a change that isn't source-compatible, we only had one occurrence that actually need to have its type clarified, which is pretty good, as far as transitioning goes.
