Fix jQuery bug #10420. Get mousewheel values from original event.

[dmethvin]

jQuery 1.7 did a spring cleaning on event properties and made them event-specific as well, so these values are no longer copied to the fixed jQuery event.

Oh, and hey @brandonaaron!!

This does not seem to suffice. I get another error a few lines below because event does not have a handle attribute.
With $.event.dispatch.apply(this, args) the plugin works again.

Please use http://code.jquery.com/jquery-git.js for testing, it is what will become 1.7.

Thanks for the heads up! I've updated the plugin to be compatible with jQuery 1.7. The one thing I did have to add was the usage of the mouseHooks to get properties like pageX/Y.
