Properly send `mouseleave` events when the cursor moves between `<iframe>`s. This allows a better handling of cursor changes and status text updates. Specifically, we do not need to continuously update the cursor and the value can be cached in the `Document`. In addition, status updates can now be sent properly when moving focus between `<iframe>`s. Note that style updates for `:hover` values are still broken, but less so than before. Now the hover state on the `Node` is updated, but for some reason the restyle isn't taking place properly. This maintains the status quo as far as behavior goes when hover moves between `<iframe>`s. This change also adds a helper data structure to `Document` which will eventually be responsible for event handling. Testing: Cursor and status change are currently very hard to test as the API test harness makes this difficult at the moment.
