Subject: [PATCH] Update example to serve the RTMP stream over HLS.

Also add some commented examples of some interesting RTMP config
options.

Adding HLS serving for example is useful for LG WebOS TV's, which don't
support RTMP natively, but do support HLS, by browsing to the m3u8
location. With this setup, one can stream to the TV, though with some
20-25 seconds of delay (as at least that much data is buffered in the
HLS playlist.. allegedly there are settings to change the stream type to
event, which might result in the client following more the latest chunk,
but I couldn't get that to work).
