Nan showed me a trick that will let us keep all of that param stuff inside of params.pp, make it a parameterized class, and still support the ability for users to specify a custom (non-system-default) pg version. This commit takes the first step towards that pattern by consolidating platform.pp and params.pp. (Everything old is new again!)
