Question, should ‘x’ and ‘y’ be localizable?

Push to history when the library mounts. Whenever popstate occurs after mounting, request to be closed.

Behavior captured in the `Modal` container. If we want to re-use this functionality for anything else that uses `ModalComponent`, just use the `Modal` container rather than `ModalComponent`.

* Add coming soon extensions to the library

This implements #1074

* don’t call `onSelect` when disabled

thanks @paulkaplan!

* add speech image to coming soon extension

With locally loaded png image

Alphabetize all the things
