Pretty print JSON to the browser for increased readability.
Pretty JSON is an extension which takes JSON output and increases the readability. This extension's output was heavily based on Ben Hollis' JSONView Firefox extension (https://addons.mozilla.org/en-US/firefox/addon/10869).
Do to limitations in Chromium, this extension does not check for a valid content type (application/json) but instead checks for "json" appended to the URL in numerous different ways.
