IsModal() now includes also the kMenuWindowLook. Fixes bug #1269. Please

review.
Added a compile time option to switch off the use of the cached menu 
windows. Looks like there is a problem with the focus system, if I keep 
the cached menu window around, it "steals" keyboard events from the main 
app window after the menu has been opened and closed once.
