[V3dot10] Report testing MinimalKernel - MNU when Opening Monticello. Later error loading SquekmapPackageLoader

[Milan Zimmermann]

Hi Pavel,

First sorry for the late reply here, i have been away for a week, and spent 
the rest (barely) catching up ... 

Thanks for your comments, a few notes inline.

OK, I will try again with latest version. If I see a problem like this, I will 
at least try to understand what causes it, or try to fix.

Does this need to run before opening the SqueakMapPackageLoader..

After having loaded both Minimal Morphic and eToys, I ran Morphic tests that 
are available (they are in categories such as EToys-MorphicTests-AAA where 
AAA=Basic, Kernel, etc). When running them, I get a question:

Which sound service would you prefer? Answering "Basic" the test continues.

There are 3 failures:
	PasteUpMorphtest
	SimpleSwitchMorphtest
	TextMorphTest
I will try in the latest version and look into the details of why. This is on 
the version about 10 days old, so the failures could have changed.

Pavel, do you mean "load the mcz which I want to test for overrides?"

Let me understand what this means: It sounds like in the Monticello world, 
an "override" is a method that exists in the MCZ that we loaded (between 
evaluating the first and second code), and the method modified it's 
methodCategory after being loaded from the MCZ (sort of "stole" the 
methodCategory from what it was in the old code) - is that a correct 
understanding? Thanks.

I will run this all over with your latest versions,

Milan
