Make parameter names optional in cache declarations

[Jesper Öqvist]

JastAdd 2.2.2

Cache declarations could be simplified to not require parameter names in the cache declaration. For example:

uncache X.y(A);

JastAdd 2.2.2 reports a syntax error for the above cache declaration, even though the meaning of it is clear. Below is a syntactically legal equivalent to the above declaration:

uncache X.y(A a);
