Merge pull request #2388 from rhamilto/sg00dwin-vertical-nav-tab-issue-2372

Automatic merge from submit-queue.

Rework nav to remove :hover selectors to address bugs, inconsistencies

Fixes #2373

Building on what @sg00dwin did in https://github.com/sg00dwin/origin-web-console/tree/vertical-nav-tab-issue2373%23issuecomment-339359101, this removes all :hover styling changes in order to forge consistency across hover, click, and tab navigation.  

@sg00dwin, @spadgett, mind pulling these changes, testing, and seeing if everything is ok?
