[IndexedDB] versionchange event gone?

Just noticed that the algorithm for updating versions refers to the "versionchange" event but the event is actually not defined in IDBDatabase or IDBDatabaseSync. Just an omission?

On a related note, I'm updating the sync API and changing the setVersion method so that it does all the version change notification dance synchronously and returns a transaction object that's the "version change" transaction. Given this behavior we probably don't need anything similar to the "blocked" event for the sync API. Any concerns?

Thanks
