#2 Add a Get Info window with stats about the URL being stalked

[Geoff Adams]

It would be nice to be able to find out some things about the image currently being viewed. For instance, it'd be nice to see the URL, the last update time, and the current re-check refresh rate (or the time of next check, or both). These are all things known internally to the code; it theoretically wouldn't be too hard to display them to the user.
