Set up Crashlytics

[flibbertigibbet]

Overview

Add Crashlytics to the project to gather crash logs, support logging analytics events (none set up yet), and to manage beta distribution.

Demo

The Fabric dashboard:

The Android Studio Fabric plugin:

Log of a crash event being sent:

Notes

The API key cannot be set via string resource, which is why the extra file was added instead. See this discussion.

Testing

• Set up the new crashlytics.properties file
• Run app
• Cause app to crash (trying to 'like' an event on the details page works)
• Should get a console log
• Should see event in Fabric/Firebase consoles

Closes #58
