updated to firebase-3.6.5 and angularfire-2.2.0

[mkobar]

I needed this badly for an angular 1 project I'm working on, so I thought I would update this seed to 2.x.

I have moved the API Keys to a private.js file (which is in .gitignore), but the private-dummy.js sample is included. And the components/firebase.utils/firebase.utils.js can now be removed, as it is no longer used or referenced.

This currently is running (and hosted on) Firebase here: https://angularfire-seed-2.firebaseapp.com/

I have updated the project.json and bower.json but have not touched or updated the test files.

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for the commit author(s). If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.

Thanks for sending this over! Really appreciate it when people contribute back. Upgrading to the latest Firebase SDK does feel appropriate.

Looks like the test units failed : (

[mkobar]

yes, I'm sure that all the test scripts / packages and test javascript files need to be updated too.

I guess I'll work on that next.
