- Got rid of JSXTransformer in test suite since it is not needed
- Simplified firebaseRef validation (we ran into a Node bug with this
old validation in GeoFire so we should change it here as well)
- Added a bunch of tests to improve code coverage
- Simplified existing tests
- Added /dist/ folder to `.gitignore`
- Replaced references to version number with `XXX_VERSION_XXX`
- Replaced all-release `CHANGELOG.md` with per-release `changelog.txt`
- Removed `release.sh` script
- Added build task to `gulpfile.js`
- Updated `npm test` to build the distribution files before testing
- Updated the dist file header and made it preserved across both
minified and unmagnified files
