Update to Ember 1.1.0 (and fix tests).

Updated Gemfile to use 1.1.0 (latest stable version of Ember).

Ember 1.1.0 does not allow items to be re-registered on a container if
they have already been looked up. This change was made
[here](https://github.com/emberjs/ember.js/commit/b8b9878bcf6517ee2b25b0e309f2a5bf5e3ff7d1).

This refactors the tests for `DS.Store#push` so that it does not throw
an errors with 1.1.0.

[BUGFIX beta] Prevent error in failed reload().
Latest ember-dev uses local packages.

Builds are only published if all files are found, but the latest
`ember-dev` requires that `yuidocjs` be installed locally (in
`node_modules/`). Since `/docs/build/data.json` (the `yuidoc`
output file) was not found, the builds were not being published.
