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.

test purposes are now reflected in GrepDialog and ReplaceDialog.  Docstrings
are improved. Initial patch by Saimadhav Heblikar

to remove duplication and return info for tests.  Rewrite corresponding tests.
Test_create_option_buttons was not testing anything because of buggy
comparisons.  Use Python subscripting to get widget options.

move two functions next to the functions that use them.

[ 634250 ] SearchDialogBase.py fix for Tk 8.4.1

SearchDialogBase refers to the grid 'col' option
considered ambiguous with Python 2.2.2 and Tk 8.4.1.
The correct name is 'column'.

text is the search term.

Rev 1.2 doerwalter
(string methods)

Much has changed -- too much, in fact, to write down.
The big news is that there's a standard way to write IDLE extensions;
see extend.txt.  Some sample extensions have been provided, and
some existing code has been converted to extensions.  Probably the
biggest new user feature is a new search dialog with more options,
search and replace, and even search in files (grep).

This is exactly as downloaded from my laptop after returning
from the holidays -- it hasn't even been tested on Unix yet.
