Title: Added basic proguard guidance

- Upgraded to latest Gradle
- Added some super basic ProGuard rules. These can be optimized a lot further, but this is better than nothing.

I tested a minifyEnabled (release) build on a KK device.

@berlinjohnson This is my first swing at ProGuard rules ever, so please do a sanity check. If they look sane, please merge.
