Swap out build script shading logic with proper shading

[Col-E]

The current shade logic works fine, but ideally we want to move these classes to a sub-package.

This way if a client is using concoction and SSVM they can use their own version of SSVM without being chained to the one we shade.

When implementing this we do not want to enable minification in the shade plugin, as that can lead to problems down the road. The dependencies we bundle in are small anyways.
