The easiest way to do this is probably to download the new version 
and save it to the old location, then use the "revert" command to 
reload the new stack. ("revert" actually reads from the disk file, so 
in this case, it will read in the version newly stored in the 
original location.)

This only works for separate stacks, however, not for the standalone 
itself. To replace the standalone, you need to download the new one 
and then prompt the user to quit and relaunch.
