Improve services API

[wondersloth]

• Owner has been updated to late bind services in the dictionary of services until the lookup() method is called.
• Service class now has a constructor with a single argument for an owner to be passed in, so that it can be bound to the object instance. Doing this allows for services to be decorated with other services.
• The services property for the options object that is passed into renderComponent and renderToString methods now allows for either an pojo, constructor, or a Service. If the value in the service map is of type Service it can be decorated with services.

Overall this looks great. Just some minor things.
