Bug 732160 - menu activation with alt-somekey makes tools stay...

Browse Source 
...in "alt-pressed" mode

Menu activation doesn't cause a focus-out becaus menu keyboard
grabbing is implemented with a simple gtk_grab_add() (the menu popup
never gets the focus). Therefore, the canvas never gets a focus-out
event and the pressed modifiers are stuck.

Fixed by connecting to "grab-notify" on the canvas, and artificially
releasing all modifiers when the canvas is shadowed by a grab.
