v2.0.0

✨ New

• Added Firebase Performance that can now be accessed via $firePerf.

‼️ Important - Breaking Change
You now have to include your appId in the Firebase config object:

config: {
          development: {
            ...
            appId: '<appId>'
          },
          production: {
           ...
            appId: '<appId>'
          }
}
