Add missing event to JQuery

What is the proper way to extend the rtd JQuery stub with more functions ?
I didn't manage to do so in my `stubs.coffee` file, and I don't think that doing a pull request every time I need a new event is the correct solution.

Also, the errors reported are not easy to understand. For example:

**template**

    Template.coinsManager.events
      "click #close_donation": (e) ->
        $("#donation_block").slideUp()

**test**

  it "hides the donation addresses when clicking on #close_donation", ->
    Template.coinsManager.fireEvent "click #close_donation"

First, my test description is incorrect. All we do here is check that the event is fired, not verifying that **slideUp** is called. Any idea how to verify that?

And if I make a typo like missing "n" at **close_donation**:

    Template.coinsManager.fireEvent "click #close_donatio"

Result:

    FAILED TESTS:
        ✗ hides the donation addresses when clicking on #close_donation

        TypeError: 'undefined' is not a function (evaluating 'TemplateClass.prototype[templateName].eventMap[key]()')

Such error makes me believe that **fireEvent** is undefined. Would be great to see the failing code with the typo in it.
