bpo-32523: Simplifying news entries with multiple paragraphs. (GH-8154)

Having multiple paragraphs in a few news entry lead to inconsistent
spacing while rendered in HTML by mixing "visually compact lists"
(when no entry of the whole list contains multiple paragraphs) and
"sparse lists" (when at least one do).

 Convert IDLE's built-in 'extensions' to regular features.
-
 About 10 IDLE features were implemented as supposedly optional extensions.
 Their different behavior could be confusing or worse for users and not good
 for maintenance.  Hence the conversion.
-
 The main difference for users is that user configurable key bindings for
 builtin features are now handled uniformly.  Now, editing a binding in a
 keyset only affects its value in the keyset.  All bindings are defined
 together in the system-specific default keysets in config-extensions.def.
 All custom keysets are saved as a whole in config-extension.cfg.  All take
 effect as soon as one clicks Apply or Ok.
-
 The affected events are '<<force-open-completions>>', '<<expand-word>>',
 '<<force-open-calltip>>', '<<flash-paren>>', '<<format-paragraph>>',
 '<<run-module>>', '<<check-module>>', and '<<zoom-height>>'.  Any (global)
 customizations made before 3.6.3 will not affect their keyset-specific
 customization after 3.6.3. and vice versa.
