Resolves #142

Still needs some testing on mobile devices.

@feimosi: Is there anything left for this to get merged?

[feimosi]

Sorry for my late reply. Not all browsers support the options argument to the addEventListener. I need to test it first so nothing breaks.

@feimosi: if you still want to support IE8, then addEventListener won't work there at all. You will need to use attachEvent instead.

I've got attachEvent fallback in the bind method already.
The problem with options is, even Edge doesn't support it, so it may treat the object as a truthy value for useCapture. I need to add feature detection code, but it'll increase the size of the script.
