This changes the internal representation of TickBoxes,
from
        Note (TickBox "module" n)  <expr>
into

        case tick<module,n> of
          _ -> <expr>

tick has type :: #State #World, when the module and tick numbe
are stored inside IdInfo.

Binary tick boxes change from

         Note (BinaryTickBox "module" t f) <expr>

into

          btick<module,t,f> <expr>

btick has type :: Bool -> Bool, with the module and tick number
stored inside IdInfo.
