Implement JavaScript parts of inserting an image in a mobile app
We must read the image file contents using a FileReader and then pass
on the data to the Online code in a message. Re-use the same
"insertfile" message used in web-based Online, but add a "data"
parameter that contains the base64-encoded image file contents.
