Added heart rate zones to the Health app.

Added Kickstart watchface.
Added the display of heart rate measurements in the sports app when a 3rd party app uses the Sports API.

Bug fixes and improvements.

Fixed a bug where the Rocky.js minutechange event was not emitted when the hour or day changed.
Added quiet_time_is_active to permit C apps to check if Quiet Time is active on a watch.
Added the alias app_package.json to the webpack.config.js file, to allow Pebble Packages to require('app_package.json'), which will require an app's package.json or appinfo.json file during JS bundling.
Added support for specifying custom PebbleKit JS and Rocky.js entry points from within a Rocky.js project's package.json file.

Added new APIs for sending custom HR data and a custom label/value from a mobile companion app, using the Sports API.
Added a helper object that will automatically manage state and message construction for updates to the Sports app on a Pebble watch.
Updated the Constant ICON_MAX_DIMENSIONS to be 25px, to be consistent with watches running 4.0 firmware. If your provided icon exceeds 25px x 25px, you will encounter a runtime error when calling customizeWatchApp.

Added support for Diorite and Emery watches.
Added new APIs for sending custom HR data and a custom label/value from a mobile app.
Added a helper object that will automatically manage state and message construction for updates to the Sports app on a Pebble watch.
Removed Bluetooth Classic support. Mobile apps compiled with this version of PebbleKit will only communicate with watches running FW 3.8 and later, which use BLE for communications. Mobile apps using PebbleKit iOS 4.0.0 and later will no longer need to be whitelisted for use with Pebble.
