Fix transformation of HTML "for" attribute

[rmoehn]

The React docs say that not only the HTML "class" attribute becomes "className" in JSX, but also "for" becomes "htmlFor" [1]. The first one was already implemented in Kioo, the second not. Implement it.

Note that this is not tested, yet, since I couldn't get the build to run on my system.

The error I'm getting is this:

$ lein cljsbuild test

I did run lein cljx once before.

If you create an empty test/test-classes directory the tests will run.

Well, thanks for the hint. I would never have thought of that. You could write it in the Wiki or the README for the next one who stumbles over it.
