Not sure if this can be merged right away because it breaks Qt4 support
If Qt4 support can be dropped, then built-in QScintilla should be either updated or just removed
If Qt4 support should be preserved, something should be done about bundled driver since the API of QSQLiteResult has changed, also CMakeLists will get complicated?
There's also a potential problem with QScintilla cmake module, because different distros may ship Qt5 version under different names
This should resolve #14
