Update docs to reflect move to transitionTo from goToState
Guard against currentState being null when sending events to StateManager

This happened when I tried to use a Router without a root state. It
doesn't make sense to send events to a state manager that doesn't have a
current state, so this makes the error message a little more
descriptive.
Guard against missing initialState

If for instance, you instantiate a Router without a root state, you'd
just get an error message saying that the currentState is null. This
clarifies to the user what's missing.
Replaces left-over reference to Ember.RootResponder
Use @type instead of @property to make JsDoc happy
