npm 1.4.22

npm 1.4.21 seems to have borked most people’s post-install processes. npm 1.4.22 should fix all of [these](https://github.com/Homebrew/homebrew/issues/31286).
npm 1.4.23

I meant to bump the npm version from 1.4.21 to 1.4.23. 1.4.23 *should* be the version that unborks everything. Hopefully.
