This is a first rough implementation of QScintilla support as SQL text editor. It should work mostly and build fine with qmake as well as cmake. The new code supports all the features of the old one plus adding a few subtle improvements. The main point of this, however, is reducing the code we have to maintain and making it easier to add new features to the editor.
