[Patternfly] Suggestion: Error-tolerant nested dropdowns

[Robb Hamilton]

I’ve used https://github.com/kamens/jQuery-menu-aim (mentioned in the CSS
tricks articel) to account for this issue on other sites.  It works well.

Note:  Bootstrap did away with submenus in dropdowns, but PatternFly
supports them as the initial implementation of the PatternFly navbar did,
so we needed to maintain backward compatibility.
