Due to image kit changes, we should revisit the demo

• trying to run Shoot demo app from Xcode6Bate3 to iPad 7.1.1 => runtime error,
• trying to run it with Xcode6Bate3 on 8.0beta3=>not able to take a picture (image kit has changed) I’ll create a jira under ios8 epic for shoot demo
• XCode 5.1.1 on iPad 7.1.1 => ok
