Upgrade scripts?

Ah, actually the package-info version in 3.9a does not support  
scripts. And MC has a bug that prevents scripts from being executed  
when the PackageInfo class does not support them (the actual error is  
supressed so you don't see it [*]). Actually they should still be  
executed on load, if you created the mcz on a system with a package- 
info version supporting scripts. And provided the binary snapshot  
loading works, as the scripts are not in the textual snapshot (which  
is another bug, but not that important).

[*] means, do not just throw an Error in the preamble - MC suppresses  
errors and presents the erroneous definitions in bulk after loading.

I fixed the first MC bug, so if you load these:

     http://source.squeakfoundation.org/inbox/Monticello-bf.277.mcz
     http://source.impara.de/Stuff/Graphics-bf.24.mcz

you'll get an Abort notice when loading Graphics-bf.24 in an unsafe  
image:

     (BitBlt canUnderstand: #displayString:from:to:at:kern:font:)
         ifFalse: [Abort new signal: 'need to load Graphics-ar.21  
first!']
