Integrate with Gradle for Scala projects

Related to #6

For Scala we could choose to invoke scalapb as a protoc plugin, or use https://github.com/CharlesAHunt/scalapb-gradle-plugin

Status: all the pieces are in place so this works by plugging into the Google protobuf plugin (see plugin-tester-scala), but it'd still be nice to have our own plugin for a readily-configured out-of-the-box experience

Fixed in #154

Are there plans to upload the gradle plugin to Maven Central or somewhere else?

Hi @gortiz - yes, ideally I think we would upload the plugin to the Gradle plugin portal (https://guides.gradle.org/publishing-plugins-to-gradle-plugin-portal), though right now we do not have this in place just yet.
