What's the point of this extra 'NewStatusText' method?  You're already 
overriding SetStatusText.  Without the NewStatusText and the setattr() 
call, when someone calls SomePluginObject.SetStatusText(), it will call 
your new version rather than the wx.Frame (or DrFrame) version -- that's 
the whole point of inheritance.  (This is true even when the 'someone' 
is the object itself, from within the DrFrame base class.  The *only* 
way to get the base class version(s) is by explicitly asking for it.)  
The extra method and setattr() don't seem to be gaining you anything.
