Create Gradle configuration

[EliuX]

I would be nice to handle the dependencies and versioning of the app with gradle and take advantage of Gradle tasks to automate certain things

Expected Behavior

Allow compilation and testing using Gradle

Current Behavior

Right now everything is done with Maven

Possible Solution

Create a Gradle configuration that can be capable of generating new versions in Maven Central

Steps to Reproduce

Compile and test the project with Gradle. When running CI on master Gradle tasks should be in charge of automating the process of changing the version and publishing it to Maven Central, among other things.
