As the text editor is still the summernote one, this improvement was
made possible through a series of hack. It has to be reviewed once the
new editor is ready.
This makes the text tools only appear in the style tab by switching to
it as soon as the summernote tools are updated. To prevent flickering,
css and js hacks had to be made.
This also moves the undo/redo buttons in the top bar with another hack:
those simulates click on the hidden summernote ones.
