Issue title: Using the API in other software?
 Issue body: Hi, not sure if this is the right place to ask, but I just wanted to make sure it was ok to use the site's API for a feature in the Elm extension for VSCode [sbrink/vscode-elm](https://github.com/sbrink/vscode-elm/). It would basically mean downloading http://package.elm-lang.org/all-packages.

Thanks :)
