NodeList: synthetic sugar events triggering

[dante]

In NodeList.js, there is commented code about possibly making the synthetic events mapped from the list (mentioned in #8415) trigger the events if called without a passed function. eg:

dojo.query(".links").onclick(function(e){ ... });
dojo.query(".links").onclick(); // trigger attached functions

Not sure if there is a technical reason behind this omission, or if it was just overlooked, but seems like a great feature to have.

we can't dig up the attached event without doing insane things like adding unique id's to all nodes that pass through query().
