Remove .once events using removeListener

[3rd-Eden]

Howdy,

When you add a new once listener on a EventEmitter, it gets wrapped in a closure and pushed in the events hash. When this is done, you will lose the reference to the original listener and lose the abilities to remove the same listener again as the removeListener checks if the supplied functions are matching..

This patch will allow us to remove the attached once listeners again, because closure function will now have a reference attached to him where we can check on.

can you add a test demonstrating this?

Merged with upstream, and updated the test/simple/test-event-emitter-once.js testcase with a demonstration.
