Delete now unneeded tk version tests and code for older versions.

This follows the previous patch that changed idlelib file names.
Class names that matched old module names are not changed.
Change idlelib imports in turtledemo.__main__.

Exception: config-extensions.def.  Previously, extension section
names, file names, and class names had to match.  Changing section
names would create cross-version conflicts in config-extensions.cfg
(user customizations).  Instead map old names to new file names
at point of import in editor.EditorWindow.load_extension.

Patch extensively tested with test_idle, idle_test.htest.py, a custom
import-all test, running IDLE in a console to catch messages,
and testing each menu item.  Based on a patch by Al Sweigart.

The new idlelib/idle.html is copied from Doc/build/html/idle.html.
It looks better than help.txt and will better document Idle as released.
The tkinter html viewer that works for this file was written by Rose Roseman.
The new code is in idlelib/help.py, a new file for help menu classes.
The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated.

Original patch by Tal Einat.

command lines.  It was broken as a side effect of the changes to
pythonw.c in b79d276041a8 for #15307.  Since sys.executable no
longer includes 'Python.app' in the path name, test for a
framework build instead.  This should give the previous behavior
in nearly all cases.  Whether the previous behavior is sensible
is left as an issue for later releases.  IDLE.app behavior was
not affected as it does its own manipulation of sys.executable.

the Apple-supplied Tck/Tk versions shipped with OS X 10.7 and 10.8.
They are not as buggy as the 10.6 version but can still easily crash.

  Issue #6834: replace the implementation for the 'python' and 'pythonw' executables on OSX.

  The previous implementation used execv(2) to run the real interpreter, which means that
  you cannot use the arch(1) tool to select the architecture you want to use for a
  universal build because that only affects the python/pythonw wrapper and not the actual
  interpreter.

  The new version uses posix_spawnv with a number of OSX-specific options that ensure that
  the real interpreter is started using the same CPU architecture as the wrapper, and that
  means that 'arch -ppc python' now actually works.

  I've also changed the way that the wrapper looks for the framework: it is now linked to
  the framework rather than hardcoding the framework path. This should make it easier to
  provide pythonw support in tools like virtualenv.
