[Cuis] New updates (Supporting packages with their own Git repository was: Loading StyledText using a script)

[Juan Vuletich]

Hi Folks,

I have just updated https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev 
. When we are happy with this, I can do a 4.3 release, as the 
enhancements to Features are quite important.

These changes include Ken's enhancements to support version ranges in 
FeatureRequisite, and a couple of new convenience methods in Feature, to 
enable things like
     Feature require: 'Sound'
     Feature require: 'Tests' version: 1.0
     (FeatureRequirement name: #'Sound' minVersion: 1 minRevision: 23 
maxVersion: 3) require

They also support Benhard's suggestion for more flexible package 
directory structure, without needing to specify the location of the 
dependences. In Bernhard's words: "a) Search all subdirectories of the 
image directory whose name starts with "Cuis-Smalltalk" (and possibly 
subdirectories named Packages?) It would rely on the convention that 
everyone names their Cuis package repositories accordingly. IMO this 
would be good anyway for consistency and SEO reasons."

I also made the fullPathName of installed packages to be cleared when 
the image is moved around, or when the saved path doesn't exist. But not 
when image is saved and stored in the same place.

Finally, I also did some misc cleanup, fixed a couple of bugs you have 
reported (blinking cursor in bold text, and failing extended clipboard 
tests), and my own fix to a bug in precedence of inherited class 
variables and globals, discussed recently in squeak-dev.

I still need to move StyledTextEditor to its own repo, and I guess a 
million other details, but I want you to try this without additional delay.

Cheers,
Juan Vuletich
