Upgrade dependency versions

[azirbel]

Upgrade dependencies so that ember-widgets can be installed without version conflicts in a new app. A good benchmark for this is installing into a new ember-cli app.

Is there any way to get ember-widgets working with CLI in its current state? I'm trying to migrate my project over, but am not seeing an obvious way to get this working at all. If anyone has got CLI working with ember-widgets 0.2, a tutorial on installation/setup/hacks would be helpful!

You can either import via bower (example: https://github.com/azirbel/minipar imports all Addepar projects from an ember-cli app), or see if the (work in progress) igillis/ember-cli branch works for you.
