Global css styles in components with ViewEncapsulation.None doesn't apply  #794

When the component's encapsulation is set to None, it's expected that the css styles in the component will be set as global. In the current implementation of the renderer, such component's use the default, NativeScriptRenderer, which doesn't apply the styles.
The fix is relatively easy - when using the default rednerer, just apply component styles with the addCss method from tns_modules/application.
