Add [email protected] development app

[kenjdavidson]

Library doesn't work due to changes to Native Modules with [email protected].

Started working on this in brance react-native-073. It's not the cleanest, but just attempting the straight conversion of the old app. There are a number of things that need to get re-written:

• Finish the conversion of the components
• Add in the local dependency to react-native-bluetooth-classic
• Look into refactoring into a <BluetoothAdapterContext> to centralize the state
