[PyCrust] Significant refactoring

[Patrick K. O'B. <po...@or...>]

I just committed to cvs the result of a fairly significant refactoring. In a
complete about-face from my original plans, I actually eliminated the Editor
class (and editor module) by merging it's functionality with the Shell
class. This means that Shell "is a" wxStyledTextCtrl now, rather than a
non-gui class that "has a" editor. There just wasn't enough non-gui code to
justify the separation. Plus, now Shell will be much easier for gui toolkits
and designers to deal with.

The fact that Editor is no longer available as a plug-in may seem like a
step backward. But the reality is that everything but the gui stuff was
already moved into other modules. So the way to get a Tkinter version is to
code a Shell class in Tkinter from the ground up, making use of interpreter,
introspect, pseudo, etc., and modeling its behavior on the wxPython version
of Shell. Any volunteers?
