Major: Intent to deprecate in favor of ember-page-title

[snewcomer]

This issue proposes sunsetting this addon in favor of ember-page-title. The last workable release would be 1.1.0. Minor bump and updates to README will follow similar behaviour to ember-i18n

There are a number of reasons to consider this.

Benefits

1. Rally around a single blessed solution for the community. Both of these addons accomplish approximately the same behaviour with little differentiation in end result. This will reduce fragmentation for users just starting out with Ember as well.
2. Will not work with 4.0. See coming Ember global deprecation found in the code here.
3. API, although at the time was a great solution, now can be accomplished through the public router service APIs.

Downsides

1. Significant refactor for those users that need to adopt a new solution.

Please let me know in this issue if you have any thoughts or concerns!

I am in the process of migrating away from this addon in favor of ember-page-title.

@snewcomer , do you have a migration path to share?

[snewcomer]

I do not. I'm not sure I would put much time into it and suggest folks find their own migration path using the docs to ember-page-title.
