Build file updates and fixes. New versions so this project can be opened in studio preview. This will allow us to use the new profiler to find the memory leaks.
According to the [Gradle Release Note](https://docs.gradle.org/2.13/release-notes)
> We've achieved performance improvements during Gradle's configuration and execution phase,
where we have measured **up to 25%** improvements to build time in our performance tests.
No changes to your build script are necessary to start taking advantage of these improvements.
