Publish "load message" and "load title"

[pcatalano]

The documentation states that the load message and title ("Vizard launching, please wait...") seen when a published exe is run can be changed using a configuration option.

The options are listed as:
viz.publish.load_message
viz.publish.load_title

Attempting to set these options and running, however, produces the following error:
AttributeError: 'module' object has no attribute 'publish'

Is there another way to do this?

The documentation also states the icon can be changed through viz.window.icon but this doesn't seem to do anything.
