Full Changelog: v1.3.0...v1.4.0

Some file hosts provide a response content type of application/octet-stream, which is not helpful in determining how to handle the downloaded file. In these cases, a best guess is made using the file extension at the end of the URL.

When a downloaded file is a ZIP archive containing multiple JSON files, a menu is presented showing the available files. The list is navigated with a simple keyboard interface.
