jQuery 1.6: jQuery.Event contstructor to support setting properties

[Rick Waldron]

Copied directly from jQuery 1.6 Roadmap:

Fix $.Event contstructor to support setting properties on the new event (not just pushing them into the originalEvent), something like $.Event({ type: "keydown", keyCode: 64 })

I couldn't find a ticket for this, if anyone knows of one that exists, please cross-ref

The resulting enhancement subsequently provides a means to "fix" an event object as well as override event object properties

A case that will be directly benefit from this:

In summation, this will allow us to depart from recommending that specified event properties (that can be found on event.originalEvent) be added by calling jQuery.event.props.push(prop). By calling jQuery.Event( type, props ), props will be available directly from the event object argument, with a value either specified by the dev (props) or copied from event.originalEvent. This "property adoption" will only be granted to the specified event type, saving all other event types from being required to copy any more properties than is actually needed of them.

Nix everything above. Simplified version here, does exactly and only what the proposal requested:
