Converting the project to use the new syntax for otype, dtype and ttytpe.
Changed prelude (gen), libcfa and test suite to use it. Added a simple deprecation rule of the old syntax to the parser; we might wish to support both syntaxes "officially," like with an extra CLI switch, but this measure should serve as a simple reminder for our team to try the new syntax.
