Added w3cid to ARIA specs

I just pushed a commit to all the specs in the ARIA and practices 
repository to add "w3cid" in the respec config for all the editors. This 
is required by the automated publication tool, which I expect to start 
using soon. I'm virtually certain this won't cause merge conflicts so I 
went ahead and pushed, but thought I should let you know why. Michael
