[Android] Add feature crash reporting

Originally, the kMAPro/src/Release folder was intended for the CI server to copy the google-services.json file, but that won't be where it gets placed now.

Removing Answers because of the setup involved with Fabric IO. Keeping this feature to Crashlytics

Using Crashlytics for crash reporting.
Trying Firebase and Crashlytics.Answers for logging events (like km_add_keyboard) for analytics

Firebase events don't persist between app launches

While legacy stable kmapro releases have analytics on the Google Play Console, Google recommends [Firebase Crashlytics](https://firebase.google.com/docs/crash/) for crash reporting.
This requires a `google-services.json` file for gradle builds. A sanitized version intended for developers/Debug variant is checked into the repo, and is associated with an appliction ID `com.tavultesoft.kmapro.debug`. The one for `com.tavultesoft.kmapro` releaeses will go on the CI servers.

Breaking change: Consuming apps of KMEA will be responsible for including the Firebase dependencies. At the moment, only kmapro has been updated.
TBD: Registering KMSamples and the Test Harness with Firebase for their own `google.services.json` file.

- Log addKeyboard as an analytic event 
- Update kmapro build.sh script to allow debug-only variant
- Add info to history.md and README.md
- Add Gradle setting so CI server can use production `google-services.json` file
- Temporarily add a menu button to force a crash. This is engineering code that will be removed once analytics in a Release build is confirmed.
