Reviewed Additional Javascript Tests

@clarkbarz reviewed the javascript tests in pull request #128, which was requested in #127. 
I don't think that handleClick should be tested like this.  The purpose of handleClick is to submit the form, but we only want to handle the form if it's a left click and the button is not disabled.

instead of testing that `it('should handleClicks')`, what we need to be testing here is that `it('should only submit if left clicked')` and `it('should not submit if the submit button is disabled')`.

Also, I'm not sure that you need to create the Event manually like that.  Can't you just do something like:

```
$('input[type=submit]').trigger({type: 'click', which: 3});
```
