Title: Don't insert settings button until header is ready. #18

4chan X can't guarantee that the header or anything else will be set up correctly when `DOMContentLoaded` is fired. This delays the settings button insertion until the shortcut container is added to the document, which should fix the settings button being missing sometimes.
