Include value along with change event

[eamsden]

The current improved-base HEAD provides the change attribute which takes an action to run in the event of a change to a form element. There is however no way to actually access the value of the form element. Ideally the value changed to should be provided to the change handler.

We should probably properly rewrite this library once improved-base is out.

That's what I've already done, and I've added lot of stuff in the process (rendering manager, components, utilities for standard elements and events) :)

but the code is still rather new and some things don't quite work properly yet or are incomplete

I think you would normally access the value through the target of the event. Apparently I commented out the export of that name in the GHCJS.VDOM.Event module and left it unimplemented, so I must have felt undecided on something. Is this correct, or is there (in pure JavaScript) a more direct way to get the value?

If the above is correct, I don't think the value should really be passed in as an argument, but there should at least be some API to retrieve it.

[eamsden]

This would require some means of reading an attribute (specifically value) from the target.

This sounds correct, but it's worth noting that the target will be a DOM element and not a VNode, which is a good thing as I'm not sure you can extract the updated value from a VNode. Is there a reason the commented-out target function has VNode as its result type?
