This is a progressive checkin.  It has the following effects:

- I have begun to swap in the ITTransientStatusWindow.  The StatusWindow,
StatusWindowController, and StatusWindow nib have been removed from the
target.  ITTSW references have been swapped in incompletely, which
results in build warnings and no window during runtime.  I am going to
use an ITTSW subclass for MT.  Everything still builds and runs.

- I rebuilt the Preferences nib.  This should be the final UI for prefs.
The biggest change is that the Cancel/Apply/Save buttons are gone.  NOTE:
I have not made changes take effect immediately yet.  I have enabled the
close button on the prefs window.

- The Prefs and Registration nibs are now saved in the 10.2 keyed
format.  I have no idea how the registration nib got modified, since
its days are numbered, but I went with it. :/
