Investigate methods of moving dependency downloads to configurations

[DenWav]

For simplicity and to just get paperweight working I have dependencies downloading in tasks using a download service that I copied from the download-task plugin. This works fine but isn't able to cache as well as Gradle's built-in dependency system.

There's some issues which makes this not a terribly straight-forward thing to do, but I have some ideas now that I've learned more about Gradle on how I can actually do this successfully. Not guaranteed though.
