[Pythonmac-SIG] update the IDLE "gentle introduction" for the Mac with new screenshots?

[Bill Janssen]

There's a nice little tutorial guide introduction to IDLE at
http://hkn.eecs.berkeley.edu/~dyoo/python/idle_intro/index.html.

It's been translated into 13 other languages by various people.

But no one has translated it into Mac by providing Mac screenshots to
replace the Windows ones there.
