[interfacekit] Small menu patch

Hi,

I looked into the Haiku project and find it pretty promising. As I
wanted to help out, I fixed one of the first small issues I encountered
when trying the OS.

The attached patch improves menu browsing. Currently, when you open a
menu in the menu bar and don't find the feature you are looking for
there, you cannot move the mouse to the next menu to make it appear;
instead, you have to explicitly click on the menu. The patch fixes this
- with it, you can just move your mouse cursor left and right on the
menu bar to browse through it's menus, similar to other operating
systems. It is really just a one-liner.

I hope I could help you with this small contribution. ;)

Regards,
Denis
