commit 8863130f9216db794d4edebb5f2f06e1faa7a5eb
Author: Joanmarie Diggs <jdiggs igalia com>

Web: Improve presentation of description lists
* Announce entering and leaving list
* Announce item count (based on the number of description list terms)
* Append the role name at the end of each description list term in
order to make it possible to distinguish terms from their descriptions
in confusing lists, while still making it possible for users to cut
off that speech in cases where the distinction is obvious.
* Similarly append the role name at the end of each description list
value.
See issue #248
