Shared scheme preconfigured to launch the Glance

Without any shared schemes, Xcode autocreates a scheme for each of the iPhone and Watch app targets, however the Watch app scheme has to be modified to launch the Glance interface. For easier use by users just wanting to see it working, I configured the scheme to launch the Glance and shared it.

Additionally, I disabled scheme autocreation so that there is only one and a user can simply click on Run to see your fabulous cat picture.
