Add Bower support. Includes committing /dist to repo.

This PR adds Bower support to list-view, and is intended to replace @geekingreen's [bower shim](https://github.com/geekingreen/ember-list-view) into the main repo. It's [registered as 'ember-list-view' in Bower](http://bower.io/search/?q=ember-list-view)

As part of this, it is necessary to commit the `/dist` files to the repo itself.

In order to maintain this going forward, the standard steps would be required:
- tag repo with semver (x.y.z) versions
- rebuild repo `/dist` for each release
- update version in `bower.json` for each release.

I'm marking the first version as 0.0.4 since @geekingreen's shim has version 0.0.3.

@geekingreen if this PR is accepted, would you please help transition your shim to use this repo itself as the golden source?
