Message 185164 - Python tracker

I got the extension from Roger Serwy's IDLEX, it is one of my favorite extensions.  In addition to adding the extension I updated the documentation both idle.rst and help.txt.  Finally I tested the patch on Mac OS X and it works great.  This patch is for 3.4 but it does work with 2.7 but the documentation for 2.7 is not synced.  Thanks.
