* Change the way the menu items are activated. Now the menubar activates on mouse down, and the other items activate on mouse up. Not everything works perfectly yet, but it will eventually allow proper usage of the shell menus by keeping the mouse button down. I believe this is also the way to go to avoid the "instant reopening" of the menus when trying to close them. svn path=/branches/shell-experiments/; revision=63671
