title: Is there a way to alphabetize package.json without installing a package?
body: <p>I've been working on lots of old npm packages that have their dependencies all out of order. They're shrinkwrapped packages, so updating dependencies is a bit of work (testing and verifying that the dependency changes didn't break anything), but I'm manually moving some dependencies from the <code>devDependencies</code> key to the <code>dependencies</code> key, and I don't want to do anything except alphabetize them before I commit. Rather than doing it manually, is there an easy way to programmatically alphabetize them with npm?</p>
