Broken in IE 8

[Willmo36]

When including the RX module in IE8, an error is thrown on bootstrap:

Object doesn't support property or method 'defineProperties'

This happens deep in the Angular stack trace so I'm not sure what line in rx-angular is causing this. But I'd guess it's https://github.com/Reactive-Extensions/rx.angular.js/blob/master/src/%24rootScopeExtensions.js#L15

Hi @Willmo36. For IE8 you can use https://github.com/es-shims/es5-shim.
