SqueakSource with diff generation

[Doug Way]

Some good news, it looks like I figured out the diff-file generation 
problem. (problem #2 below)

I managed to put a halt in the diff generating code that was being 
executed, and found it was in an infinite loop trying to create an 
error stack caused by a different problem.  The infinite loop was 
because SocketStream>>printString is broken (in 3.7/3.8/3.9, I'll post 
a fix).  After fixing that, I got a different infinite loop because it 
was trying to email the error stack somewhere (maybe configured to 
Bert's address), which caused a connection error, which then tried to 
email another error stack for that, etc.  I might be tempted to just 
dump error stacks into a log directory on the server rather than 
emailing them, hm.

Anyway, after fixing that, the root cause of the error was because I 
did actually have the wrong version of Monticello loaded, which I was 
trying to get around the SimpleServiceEntry problem earlier.  Loading 
the version specified by Bert fixed that.

So, .mcd file generation is working nicely, and using 
#updateFromRepositories and #upgrade on the MCConfiguration map from a 
client image appears to work, which is how the automatic updating will 
work.

I'd still like to fix problem #1, though, since the SS image will be a 
bit crippled with my hack in there.  Then I will try replacing the SS 
image at http://source.squeakfoundation.org and see how it goes...
