hili av Francis

Adds a small function to pages that lets you select text or images and right click to send the selection as JSON a web server.

If you are offline, hili queues the snippets to send when a connection returns (you need to leave the tab open until they are successfully sent; there's a little indicator that lets you know how many snippets are queued).

See https://github.com/frnsys/hili for more information.
