Proguard support for Android SDK

We have added support for Proguard to our Android SDK, from release 1.2.1.

It has been added on a library level, so the only thing you need to do in your project is to add/set minifyEnabled true in your build.gradle file. We have tested it extensively in our internal builds and our Showcase app, but if you find any problems, don’t hesitate to reach out or open an issue on Github.
