JSX props map to object properties

[mindplay-dk]

JSX props map to object properties by default and falls back to attributes - except for SVG elements, which always use attributes.

Closes #46

I will add some inline notes to the PR in a moment.

Since I don't know how to get the tests working yet, there are no tests for this yet.

You can see working examples here, including both class and className working now, readOnly property working with a literal true, and SVG element with attributes rather than properties updating correctly, text nodes updating with nodeValue, and <input> elements updating with value.

Hey, I'm back.
I see that use cases work great, so merge this request first~

Thank you very much.

I don't quite understand why it can support className. How does it work??

The test for name in dom will detect it and set it - for example:

console.log("className" in (document.createElement("div"))); // => true

This will cause the property to be set.

As opposed to:

console.log("class" in (document.createElement("div"))); // => false

This will continue on to setAttribute() as before.
