HtmlHelpers needs to use @inject for activation

[pranavkm]

• Need to prepopulate some well known services that get injected by default into views.
  This includes IHtmlHelper for now. Might need to expand (IUrlHelper?)

IUrlHelper and IViewComponentHelper

We need to ask if these helpers @rynowak mentions need to come through @Inject - The main reason to use @Inject for a property is to replace the signature, not to replace the implementation. For just activation we still probably just need to decorate the existing properties with [Activate]
