[Pythonmac-SIG] universal binary installer, take 1

[Bill Janssen]

Ron,

For this release, we were going to change the name of the folder that
the IDLE appears in, from "MacPython-2.4" to "Python 2.4".  In this
installer, it seems to be "MacPython 2.4".

I think it would be a good idea to remove the old "MacPython-2.4"
folder, as well.
