We previously had Variable as a common ancestor for Placeholder and Parameter. This reorganizes things a bit so that:
There's no Variable
Placeholder is now Column
Constant is now Scalar
This is in anticipation of changing Column to be considered Constant (so that you have a Constant super trait over Column and Scalar). However that is a much bigger change that's hard to see to the end of, so for now Column is still NonConstant.
This also dumps rainier-cats and rainier-scalacheck.
