These can be used to determine the goal line used by the Pebble Health app. * Added ``HealthMetricRestingKCalories`` and ``HealthMetricActiveKCalories`` to retrieve Calorie burn information from Pebble Health. * `CFLAGS` and `LINKFLAGS` env variables are now correctly honored by the app build process. * JSON files under the `src/js/` directory are available to `require` in newly-created projects. * ``persist_write_bool`` and ``persist_write_int`` are now correctly documented to return the number of bytes written on success.
