correct _removeEndTransitionListener
fade does include the root element

the FadeMixin does not do anything when this.getDOMNode() element has a
fade. This causes a bug at least in the Modal when the backdrop=false
and the Modal component is the root, causing it to never fade in.

Future proof cwp, remove unused internal utils

Adds a version check to cwp so that it only wraps `child.type` in a mock
factory for version 0.12, as it would break in 0.13, where
`react.createElement ===
require("react/lib/ReactElement").createElement` will be `true`
NavItem includes anchor attributes on the li tag

`{...this.props}` passes DOM attributes to the li tag incorrectly.

I "fixed" this by turning on the harmony features in grunt-react, and
using the spread operator which is the recommended path from React. We
can just as easily do this manually
