- extended the grammar so that the DECORATE function declaration list can almost be used as-is, with the sole exception of requiring any action function to declare a return type, even if it is void.

This adds:
 * builtin types color, state and sound.
 * ending a parameter list with an ellipsis to declare a varargs list. (A_Jump uses this.)
 * allowing to declare optional arguments by giving them a default value.
 * adding an 'action' qualifier for function declarations.
