LPS-41024 - Add content menu components are not consistent with other responsive components

Hey @natecavanaugh,

Attached is an update for http://issues.liferay.com/browse/LPS-41024.

NOTE: "In the ticket, Juan calls for the search input to use the mobile responsive nav-bar-search component. But there really ins't enough room in the side panel for that. Plus if we put that search input into the nav-bar, it would be inconsistent with the add application panel." - @Robert-Frampton

Please let me know if you have any questions.  Thanks!
