With this it is possible to post a photo note with a description, nothing
more. It doesn't move the file in the file system, just posts it from
the temp location to the users server. It also does validate for file size,
content type and max upload size and shows the errors to the user.

If everything goes according to plan the response from the users server
is shown, together with a link with the posted photos URL.

Support reply bookmarklets, and hopefully the Firefox Social API
"Share" provider too.

This changes the value of "in-reply-to" to use hyphens instead of underscore separators!!
