Consider non-TK style implementation

[burnbrigther]

Hi Duncs - I use a clusterssh fork you probably know called csshX on mac osx. I really like how cleanly hotkeys work with the interface and how easy it is to control window placement. I don't know if this is due to the underlying mac implementation of the terminal app - I'm not an expert in this area. The only clunky thing with that implementation is the Control-A activation sequence which is used for many other things, but is in fact configurable. Without know what it would take - would you ever consider moving in this direction?

The next 'big' piece of work I have planned for the code is to move the use of Tk into a separate module rather than be in the main code. When I have done this I can then look at adding other window libraries such as Gtk2 and potentially something specific for the Mac.

So, yes, changes to make this possible are in the pipeline, but, as always, it is finding the time to get the code done.
