Another interregion comms change that will not work well with previous versions. This commit moves InformRegionOfChildAgent from OGS1 to RESTComms, effectively having the complete child agent life cycle over REST: create=POST, update=PUT, close=DELETE.

Additional changes include more functions in the IHyperlink interface, and some refactorings in the HG code for better reuse in RESTComms.
