Add support for object event handlers (using handleEvent)
- `handleEvent` is checked on dispatch, like in the DOM. - Had to reorder attribute key checking so `undefined` events still got removed. - Drive-by: Optimize the initial attribute key checking a little. - Drive-by: Fix changelog v2.0.0 link in TOC.
