Default initialize function argument, closes #1090

[sookach]

@hsutter @bluetarpmedia This patches #1090 by allowing defaulting of arguments in a function call by use of '()' (akin to '{}' in C++).

Looks good, a regression test would be nice.

Yeah, it passed on my fork https://github.com/sookach/cppfront/tree/pr/default_arg

but it looks like the tests don't run on their own in this repo?

Ah, what I meant, is that it would be nice if you add a regression test for the new feature. Sorry for the misunderstanding.

[sookach]

Cool, added a regression test. Let me know what you think.

Thanks!
