[Cuis] Updates

[Juan Vuletich]

Hi Folks,

I did a new commit/push to github.

Biggest news is that I integrated Masashi Umezawa's FileMan into Cuis 
base image. The objective is to replace the FileDirectory and 
DirectoryEntry hierarchies with a simpler and more consistent API. Tests 
are in the Tests.pck.st package. I added a few new tests, and tweaks to 
the code to make them pass. Check the changesets and tests if you're 
intetested (feedback very welcome). You can nos start updating your 
code. After all users in the image and packages are updated, we'll 
remove the old API (or move it to SqueakCompatibility.pck.st), and name 
the result Cuis 5.0. Thanks Masashi-san!

After some comments on squeak-dev, I made some punctuation marks 
slightly larger and easier to see at mid-small font point sizes.
Original glyphs available as option. Also, Dan Norton updated the 
TerseGuide.pck.st package.

Also, minor tweaks here and there, and in some optional packages.

Cheers,
Juan Vuletich
