Version 2.0.0 Alpha 5 (#178)

* [`babel-plugin-es6-promise`](https://www.npmjs.com/package/babel-plugin-es6-promise) removed from `.babelrc` and dependencies (attempt to
fix #175)
* [`babel-preset-stage-1`]() removed from `.babelrc` and dependencies (unneeded)
* Properties on `FirebaseConnect` initialized using [property initializers syntax](https://babeljs.io/docs/plugins/transform-class-properties/) instead of constructor
* [`transform-decorators-legacy`](https://www.npmjs.com/package/babel-preset-decorators-legacy) only applied in test environment
