/**
* Created by Allan Wang on 2017-08-15.
*
* Due to the nature of facebook href's, many links
* cannot be resolved on a new window and must instead
* by loaded in the current page
* This helper method will collect all known cases and launch the overlay accordingly
* Returns {@code true} (default) if action is consumed, {@code false} otherwise
*
* If the request already comes from an instance of [WebOverlayActivity], we will then judge
* whether the user agent string should be changed. All propagated results will return false,
* as we have no need of sending a new intent to the same activity
