Support creation of arbitrary gradle artifacts #35
Description
The initial goal of this project was to build Gradle Applications that apply the application plugin.
This is an arbitrary limitation and there is no technical limitation that prevents us from also building jar,war or any other files or data.
Therefore, I propose a new buildGradleArtifact builder function that can be used for that purpose. The buildGradleApplication builder function stays the same but uses the buildGradleArtifact function internally.
