3.0.0

Major changes:

• Support for Pebble Time Round
• Support for 8K AppMessages
• Support for Swift
• Support for Bitcode

Breaking changes:

• All appUUID properties are now NSUUID instead of NSData
• As soon as you set the delegate and the appUUID you must call run the central before you'll get any connection events:
  [[PBPebbleCentral defaultCentral] run]

Tips:

• Add bluetooth-peripheral and bluetooth-central to your UIBackgroundModes if your app should work while in the background
• No need to check for lastConnectedWatch.isConnected at app launch anymore. Just wait for the event after you invoked run
• We removed PebbleVendor. Keep it if you need it. Drop it otherwise to reduce the size of your app.
