Drop the QTextEdit widget in the Edit Database Cell dock

Browse Source 
Use the QScintilla widget for all the text modes of the Edit Database Cell
dock. All the features are believed to be preserved.

- The plain text mode is materialised removing the lexer.

- Null values are indicated now in the margin instead of using a
placeholder. The same pattern is also used for the Image and BLOB data
cases when the editor is switched to a text mode. In the dark mode, the
line number margin matches now the style-sheet and instead of the
configurable editor colours.

- Read-only state in the editor is hinted by the caret not blinking, but
the text is still selectable by keyboard or mouse.

Features and fixes added by using this widget:

- Find/Replace dialog for the plain text editor. See issue #1746
- The QScintilla widget does not strip CR characters. See issue #1793
- Line numbers and visible caret line in the text mode.
