Implementation status of "Additional Requirements for Bidi in HTML"

Here is an implementation status
document<https://docs.google.com/document/d/17nb3wlYkIG9MNtL1mlXVPOVe4QwyApiHRYim3nTi5CE/edit?hl=en>
summarizing
the status of each proposal. I will continue to update it as the status
continues to change.

If some part of the status is not to your liking, you are most welcome to
contribute to the discussion on the various bugs and threads linked by the
document while it is still possible to change things. Or, if you can try to
get a consensus here on public-i18n-bidi first.

Regards,
Aharon
