Add option to pass through CLI flags but ignore node and v8 flags

Based on [issue #39](https://github.com/crcn/nexe/issues/39).

`-f, --flags Don't parse node and v8 flags, pass through app flags  [default: false]`

Finds and comments out lines in src/node.cc

Also added node-progress to package.json dependencies and defined _log in monkeypatch.js
