Bower and versioning

The same as https://github.com/Addepar/ember-table/pull/148, with some changes:
* No more dist repo for now. We'll do that in another step.
* Rebased, and put the dependency removal in a separate commit. Just look at the more recent commit for meaningful changes.

What this does:
* Move many dependencies to bower
* Set up process to release to this repo
* Use grunt-text-replace and release-it to bump version numbers
