Syntax error with JS codegen

[Christian-W. Budde]

The below code:

procedure log(data: Variant); external 'console.log';

log(1 - sin(4) * Random);

results in

console.log(1--0.756802495307928 * Random())

Which is obviously invalid. It’s also invalid variable expressions instead of the constant 1.

Fixed Issue #176 + test + simplified CodeGen output and removed redundant code
