mostly bug fixes from previous releases. Cleans up a number of http header related issues, utilises the same code for work on POST. A more complete switch over update (the ability for one stream to be swapped with another, eg source client replacing a relay). A new mount setting (linger-for in seconds), to keep a stream around after termination for cases where you want either someone else to jump in (switch over) or add a delay if you expect the feed to re-establish in some short time frame.
