Example fix, test script, and some refactoring

- The test script just does an eslint check. (Closes #121)
- Refactored JS code to pass the check.
- Fixed VideoPlayer example. (Closes #117)
  - Updated package.json to use local react-native-video in a simple manner.
  - Added shared scheme for target.
  - Updated poject settings.
  - Now using react-native 0.18.1.
