ISSUE-361: Add ttm:mediaTimestamp (or equivalent) attribute. [TTML2]

http://www.w3.org/AudioVideo/TT/tracker/issues/361

Raised by: Glenn Adams
On product: TTML2

Define ttm:mediaTimestamp attribute (or equivalent) to allow author to explicitly associate a related 'begin' time in the document's time space with a specific timestamp in a related media object's time space. For precedent, see [1] for definition of X-TIMESTAMP-MAP.
