 The get_icon() method of ActivityBundle is problematic because it
 sometimes creates a bogus temporary file, depending on whether or not the
 ActivityBundle is zipped or not.  A get_icon_data() method would fix this
 interface problem.

 The activity updater needs to access the update_url field in
 activity.info; a get_update_url(self, default=None) method should be added
 to do this; it should return the 'default' parameter if no update_url is
 provided.

 I'll attach a patch when I get time later.  There are some ContentBundle
 method fixes I'm working on which I'll fold into this bug as well.  9.1
 time frame; working around this for 8.2.
