Make TextEditor setup more flexible

Browse Source 
So far it was only possible to combine TextEditorFactory, BaseTextEditor
and TextEditorWidget directly.
That TextEditorWidget is also directly a QPlainTextEdit made it
impossible to "decorate" the text editor widget with something else
without a lot of effort.

Make it possible to create a text editor factory that returns an
arbitrary widget, as long as it can be "cast" to a TextEditorWidget with
either qobject_cast or Aggregation::query. That way the TextEditorWidget
instance can be attached to the editor widget via Aggregation.

Adapt other code that accesses TextEditorWidget from editors
accordingly. Introduce a common method how to do that.
