Added countcomments action
Show only comments if container is defined

Make showing comments optional, so commenter.js can be used
for other things like filling in comment counts
Move data-object-id to container div instead of script tag
Functionality to fill comment count containers
Ability to find objectId on parents of container
Count comments in example.html
Update comment counts after rendering comment list
Count only comments on list reset (thus after change)

This saves an extra call to the backend
fire change event to commentContainer if updated
Only run countComments() if no list rendered
don't show counter if there are no comments
