I've been wondering why SUnit doesn't show up as an installed package 
in the SMLoader in the current alpha image anymore... it seems that 
this somehow happened during the upgrade to SM2.

For example, start with an earlier (Basic) image such as 3.6-5429-basic 
(from the ftp site).  If I open the package loader and choose not to 
upgrade to SM2, I see these as the installed packages:

PackageInfo (1.30)
SARInstaller for 3.6 (19->18)
SM Package Loader (1.02)
SUnit (3.1)
SqueakMap Base (1.07)

If I close the loader and re-open and upgrade to SM2, I see these as 
the installed packages:

MCInstaller (8->10)
PackageInfo (1.30->14)
SqueakMap2 base (0.96)
SqueakMap2 loader (0.92)
VersionNumber (1.0)

So, it seems to have lost track that SUnit, SARInstaller, etc., were 
installed.

Not a major problem, I guess, since if we do an in-image update of one 
of these packages (e.g. SARInstaller) to a newer version, it will show 
up then as installed.  But still, I was getting confused as to which 
code in the alpha image is being tracked as packages, etc.

(I ran across this problem because I was trying to figure out if Test 
Runner Enhancements is an in-image package.)
