Gui: ActionGroup - aboutToShow and aboutToHide

Browse Source 
==============================================

ActionGroup may integrate a drop down menu (internally a QMenu).

QMenu has signals aboutToShow and aboutToHide, which are called just before showing/hiding the menu.

This commit extends ActionGroup by providing corresponding signals.

An ActionGroup can be added to more than one toolbar and thus creates more than one menu. So, it can theoretically
happen that you have opened a menu and click on another menu. For this reason, the menu is passed as argument:

void aboutToHideMenu(QMenu*);
void aboutToShowMenu(QMenu*);
