Got rid of the python.rsrc resource file. The error message strings and

dialogs are now stored in Mac/Lib, and loaded on demand through macresource.
Not only does this simplify a MacPython based on Apple's Python, but
it also makes Mac error codes come out symbolically when running command
line python (if you have Mac/Lib in your path).

The resource files are copied from Mac/Resources. The old ones will disappear
after the OS9 build procedure has been adjusted.
