UI

* Node buttons can now use the layout engine. a few simple
  ones are converted. We'll keep this code in C for now,
  python wouldn't help much here.
* For node buttons not using the layout engine, manually
  computing the button height is not longer needed.
* Node inputs are still not RNA wrapped, would be good to
  have these available as well for keying, but makesrna does
  not have access to the bNodeTypes.
