Set prototype of LivefyreContent to new object, dont extend
LivefyreStream.createContent does not try to create LivefyreContent if no state heuristics match
LivefyreReverseStream can have plugins added to process states that the default implementation cannot convert to Content
Add View#setElement and #render
LivefyreReverseStreams can now be created without a headDocument or page, and will request init themselves. The init response can also be passed as .initData on construction
