Sync the Touch-related interfaces with the two specs

Unfortunately there does not appear to be a single well-maintained spec
that deals with all of this, but these documents from the Touch Events
Community Group seem to be the most recently updated:
http://rawgit.com/w3c/touch-events/v1-errata/touchevents.html
http://rawgit.com/w3c/touch-events/master/touchevents.html

There are no changes to the generated code except for changes in order.
