ttcn: Skip comments correctly

Right now comments don't get skipped all the way, leading to code like

    type enumerated Enum {
        /* a comment */
        Value
    }

or

    type enumerated Enum {
        // a comment
        Value
    }

resulting in "Value" not being present in the output
