no release, no Swing

Its been a long and difficult weekend. I worked too much and the code & design suffered for it and that led to more overworking. I'm still working on the interfaces!

UI is now threadsafe.
The ScriptUI has been dropped and a ScriptClient has been added.
Found some old bugs, too.

Still there is one change needed to the Portal interface--the newChannel method needs a parameter which names the type of UI needed. Of course, that means that I need to build a hash map of (thread safe) UI objects. So I'll want another file which maps UIName to UIClass.

And still I need to update the Swing code I have, such as it is. But right now I'm bushed. :-(
