Matthias Clasen d68d78de81 Only show the mnemonic underline when pressing Alt
...and show them in menus when navigating the menu with the keyboard.
This is similar to what other platforms do, and reduces visual clutter.
There is a setting to control this. Most of the work on this patch was
done by Thomas Wood. See bug 588554.
