Applied patch by Pete Goodeve from ticket #7182. It improves

keyboard navigation/tracking of BMenus and BMenuBars, although
many issues remain.
Should not yet go into alpha, since there is one issue which
I am not sure if it's not a regression. The issue is that
invoking a menu item with Enter for the first time seems to
have no effect, while invoking it subsequently works as
expected. I don't know, yet, if that's a regression of this patch.
In any case, it's better than before, thanks, Pete!
