Update .jshintignore for mocha-jshint.

Speeds up `npm test` quite a bit (the subfolders here were still being
searched).
Squelch function inside loop warning.
Use static array to confirm vendoredPackage output.

I would definitely prefer to compare output directories, but we can't
add empty directories to .git (and adding a `.gitkeep` makes it included
in the comparison results).

Once we move to funnel, this won't be an issue (it doesn't make these
empty subdirs).
