LPS-32488 - Add portal.properties setting to open Dockbar Manage links as maximized portlets or iframes

Hey Nate,

Attached are the changes we made to allow the dialog iframes to be opened as maximized portlets.  This update can be found at http://issues.liferay.com/browse/LPS-32488.

NOTE: Shinn pointed out to me that with this change to the dialog iframes, we reverted some of the logic which was added from http://issues.liferay.com/browse/LPS-21008.

Please let me know if you have any questions.

Thanks!
