bin,lib: remove extra comments/lines/spaces

- Removes "module dependencies" comments and things that, IMHO, don't add
too much value. Happy to add back if helps some people when reading
through `node-gyp`.
- DRY up `lib/process-release.js`.
- Removes a bunch of extra blank lines, as well as random spaces.
