Offer IckleFragmentActivity via an alternate hierarchy

Only android.support.v4.app.FragmentActivity and android.support.v4.app.Fragment will be exclusively supported via alternate hierarchies with com.lonepulse.icklebot.activity.support.IckleFragmentActivity and com.lonepulse.icklebot.fragment.support.IckleFragment respectively. All other specialized activities and fragments must use the IckleSupportManager (either by itself, or together with an IckleSupportFragment).
