This patch is an extensive refactoring of help.txt and idle.rst. The first thing I did was merge issue5066.patch from jesstess into the current idle.rst file, because the original patch from jesstess was so old it had to be merged by hand into the 3.4 source code.  Then I compared what the merge document said with the actual menus of IDLE and made several corrections because of missing menu options.  Finally I refactored the help.txt based on idle.rst and created the resulting patch. Several capitalization's were fixed along with many inconsistencies between the two files.  

I have not tested on 2.7 only 3.4.  My plan is to test with 2.7 and create another patch by end of the week 12/2/2012.
