The comments at the beginning of config-main.def describe the
configuration files and the design implemented to update user
configuration information. In particular, user configuration choices
which duplicate the defaults will be removed from the user's
configuration files, and if a user file becomes empty, it will be
deleted.
The configuration database maps options to values. Conceptually, the
database keys are tuples (config-type, section, item). As implemented,
there are separate dicts for default and user values. Each has
config-type keys 'main', 'extensions', 'highlight', and 'keys'. The
value for each key is a ConfigParser instance that maps section and item
to values. For 'main' and 'extensions', user values override
default values. For 'highlight' and 'keys', user sections augment the
default sections (and must, therefore, have distinct names).
Throughout this module there is an emphasis on returning useable defaults
when a problem occurs in returning a requested configuration value back to
idle. This is to allow IDLE to continue to function in spite of errors in
the retrieval of config information. When a default is returned instead of
a requested config value, a message is printed to stderr to aid in
configuration problem notification and resolution.

Item 'name2', is used for built-in ('default') themes and keys
added after 2015 Oct 1 and 2016 July 1. This kludge is needed
because setting 'name' to a builtin not defined in older IDLEs
to display multiple error messages or quit.
See https://bugs.python.org/issue25313.
When default = True, 'name2' takes precedence over 'name',
while older IDLEs will just use name. When default = False,
'name2' may still be set, but it is ignored.

ConfigChangesa Manage a user's proposed configuration option changes.
Names used across multiple methods:
page -- one of the 4 top-level dicts representing a
.idlerc/config-x.cfg file.
config_type -- name of a page.
section -- a section within a page/file.
option -- name of an option within a section.
value -- value for the option.
Methods
add_option: Add option and value to changes.
save_option: Save option and value to config parser.
save_all: Save all the changes to the config parser and file.
delete_section: If section exists,
delete from changes, userCfg, and file.
clear: Clear all changes by clearing each page.
