Stratego Core Language

The syntax definition of Stratego is organized by syntactic category (Strategy, Term, etc.). This makes it hard to distinghuish syntactic sugar from core constructs. Refactor the syntax definition to make this distinction clear. This is also useful for static checks on the components of the compiler, i.e., to verify that only a restricted set of constructs is used at some point in the compilation process.
