Record the 5 most recent API requests and responses with RecordResponseInterceptor

Catch and report exceptions
- Run the Android loop with a custom exception handler
- Display otherwise uncaught exceptions in CrashReportActivity
- Allow the user to share / copy the crash data, and restart the app
- Include the most recent API requests/responses in the crash data

All of this only happens in debug mode, and the user has to take specific action to share the data, nothing is shared automatically.
