delete proxy trap not implemented

[matthewp]

Observations occur when:

object.foo = undefined;

But not when:

delete object[foo];

occurs. Probably just need to add some ObservationRecorder.adds?

Probably just needs to dispatch an event similar to set.

Actually this can't easily be implemented. define() sets up property descriptors, and therefore delete foo.bar will not hit the proxy trap. You'd have to add another proxy on the instance itself, I think.
