LPS-44543 - Tapping each successive icon on the Dockbar on a mobile device does not close previous menu

Hey @natecavanaugh,

Attached is an update for http://issues.liferay.com/browse/LPS-44543.

NOTE: "I added the toggleTouch attribute to the navItem taglib because we didn't have a way to turn that functionality off.

I also changed how we were handling the site navigation menu toggle, before it was just using the nav collapse toggle button from the nav tag. By using that toggle button, we had two event listeners that were both toggling the open class on the trigger, which obviously was producing some inconsistent behavior.

I left collapsible turned on for the nav tag, because if we remove it, we'll break a lot of styling in dockbar.css and custom.css. This way it's least destructive, and we can leverage the styling that's being done to the other nav items in mobile view to style the nav item I added. Let me know if you think we should change that." - @Robert-Frampton

Please let me know if you have any questions.  Thanks!
