Event Failures

Related: #https://github.com/choojs/nanomorph/issues/89

I created tests for the events listed in https://github.com/choojs/nanomorph/blob/master/lib/events.js#L32

The following events fail to parse from HTML attribute. I believe this is a problem in bel. But I am not sure where this problem originates.
- onfocusin
- onfocusout
- ontouchcancel
- ontouchend
- ontouchmove
- ontouchstart
- onunload

**The first two are listed as problematic and fail**

> Note: these event may not work as expected in Chrome, Safari and Opera 15+ using the JavaScript HTML DOM syntax. However, it should work as an HTML attribute and by using the addEventListener() method (See syntax examples below).

onfocusout

**These events are listed as Editor's Draft(Non-stable version), but should work in chrome. They also fail.**

ontouchstart

**This event should only work on the body tag, but also seems to fail.**
onunload

Should only work on the body tag. Testing on the body tag fails.

I will submit a pull request that contains the event tests.

**Note: Failing tests have been commented out.**
