FEATURE: Add optional 'queryUriConverter' to Renderer to allow different uri conversions for calendar pages then replays.. This is useful for proxy mode
where the calendar/query page may specify explicit timestamp but the replay uri does not.
URL PARSER: Add support for 'data-src' and 'data-uri' attribs to div and li tags.. somewhat experimental (as any data-* attributes may be added to any tags)
but for now testing specific examples with these common use cases
