LPS-49268

Hey @natecavanaugh,

Attached is an update for http://issues.liferay.com/browse/LPS-49268.

NOTE: We are hiding the ```box-shadow``` on all ```portlet-options.btn-group``` because of how we are implementing the ```portlet-options``` cog in Liferay.  Bootstrap adds the ```box-shadow``` to ```btn-group```, and in cases where this is in a menu/drop down the drop shadow makes sense like in changing the display view of Web Content.

The ```box-shadow``` does not make sense for for the cog icon because it is just an icon.  We can add a text-shadow to achieve the same desired affect from Bootstrap if we would like or we can remove the ```box-shadow``` altogether like we did in this pull request.

Please let me know if you have any questions.  Thanks!
