Doesn't correctly check version on devDependencies

[gnarf]

See npm/read-installed#4 for the upstream issue.

npm ls currently doesn't properly check devDependencies

Ben put together a custom check that we could adopt if those upstream issues don't get resolved: https://gist.github.com/cowboy/5067251

+1 on adopting that implementation, since this is still an issue 11 months later.

Ben's check iterates over the specified dependencies, so unlike npm ls, it doesn't care about dependencies that shouldn't be installed (since they aren't listed).

Though we've been using this plugin for various jQuery projects and I don't think the npm ls issues were ever a real issue.

Patches welcome!
