Support changing uid/gid from the vinyl object to the file on disk

[phated]

We now allow mtime, atime and mode to be set on the actual file if they exist on the vinyl object. We should also support uid and gid through use of fs.fchown.

@erikkemperman @piranna would either of you have time to look into this?

Probably not much, swamped at work.

For what it's worth, I expect this to be pretty easy to implement but annoying to test (cough-windows-cough).

Sweet!

Looks like this was fixed. However, I still see a chown fail

sindresorhus/gulp-chown#5 (comment)

using gulp-chown. That was originally pointed at vinyl-fs as the culprit, but I've installed vinyl-fs#master, and still see the problem. Just checking in to see which thread to pull on -- gulp-chown, gulp-dest, or still vinyl-fs .., ?
