Cannot pass an Array byval

This commit only affects the Symbol Table.
The parser still has to allow the syntax and use this method.

Also fixes a typo.

Also fixes a typo.

The size of an array passed by ref in the stack is
the size of it's pointer (2 bytes for Z80)

 * Arrays will be passed always by Ref
 * Uses the same syntax as in FreeBasic
 * Allows different array-bounds to use the same function

Still some extra checks pending

Checks a function with array parameters is being called correctly.
Also test updated.

When invoking a function check also their arguments
(var, arrays) matches correctly.

Only for numerical types

This requires now to have uinteger type
