Replace substitution function with a map
It makes using variables with queries more approachable, but some work still has to be done. - The type `Subs` should be renamed and moved out of `Schema`, together with `AST.Core.Value` probably. - Some kind of conversion should be possible from a user-defined input type T to the Value. So the final HashMap should have a type like `HashMap name a`, where a is an instance of a potential typeclass InputType.
