Service got renamed to flash-messages-service but docs need to be updated

[technomage]

The readme shows service injection with flashMessages: Ember.inject.service(), but the new name is flashMessagesService. Same for the case where you pass in a name: Ember.inject.service('flash-messages-service'). I am running into this from an add-on that is using ember-cli-flash 1.0.0.

Still looking into it. My application that uses ember-cli-flash where I am trying to extract the add-on still works with the old api, so it is probably something in my add-on setup or test setup.
