[UI] Gary's UI Enhancements

Hello all!

I have been using the UI enhancements, and found that it isn't actually closing system windows - especially debugger windows. If I run code like:

(Debugger allInstances collect: [:d | d dependents detect: [:i | i isKindOf: SystemWindow]]) do: [:w | w openInWorld]

I was getting 7 or 8 debugger windows popping up on the screen, they just wouldn't close. I had to start over with a fresh image and load my code. Now that I'm not using the UI enhancements, I don't have this issue, but I sure miss them!
