Mostly, removing things that were never intended to be exported publicy.
BREAKING CHANGE:
The following are no longer publicly exported APIs. They were intended as internal
utilities and you should use your own util:
```
browserDetection,
dispatchEvent,
el,
normalizeCSS,
stringifyElement,
expect (and custom matchers for Jasmine)
```
There is no need to expose this additional method inside of the Renderer
API. The functionality can be restored by looping and calling
`setElementStyle` instead.
Note that this change is changing code that was was introduced after
the last release therefore this fix is not a breaking change.
