Support view injection via JSX

It should be possible to let views be injected when using JSX expressions.

One option is to let `createElement` first check the attached injector for injectionHandlers of that type. If they are present, use that handler, otherwise create instance directly. To pass the creation properties a new decorator `@injectionParam` could be used to mark a parameter index for passing the injection parameter, or an option of `@injectable`. Or just assume it's the first parameter.
