Doc: Changed CSS text-align from "justify" to "left".

-Documentation looks weird when viewed in a narrow window because
 much of the text are long.
-Qt Project's CSS uses "left".
-This change affects any documentation which uses the global
 templates.

QButtonGroup - add buttonToggled signals

QButtonGroup emits signals on clicked, pressed and released for
buttons in the group, but for some (insuffienct) reason it did
not emit anything for toggle (the only signal that it didn't emit
anything for).

This patch changes that, by adding handling of that signal to
QButtonGroup.
