Fixes:
- Keyboard navigation using submenus (acts similar to right-click in Mac, going up first starts to top of list, bottom the bottom - moves from there, etc. Only difference is that the submenus display on item focus)
- Takes into account the
.dropup,.dropdownand.pull-leftmodifier classes. E.g. If it's pull-left the left and right arrows switch around, if it's a dropup submenu - we start by focusing the last item vs the first which is at the top. - Touch navigation now works prevents the default click events from happening with the delay
- [esc] key will bring you back in focus with the initial button no matter where in the dropdown you are
- Adds a item visibility selector to only navigate through visible items
