SF: Workaround for Igor not changing subwindow focus on right click

There is a bug, where Igor does not change the focus to a subwindow when
right clicked. This prevents that the clicked window name can be retrieved
on the basis of the currently active window.

WM suggested a workaround where the last right clicked window is stored in
a window hook and then used in the menu handler.

This commit implements this workaround.
