site.py documentation does not mention special objects help, quit etc added to builtins

[stevendaprano]

The site.py documentation does not mention the special objects that it adds to builtins:

• help
• quit and exit
• license viewer
• copyright and credit strings.

(Have I missed any?) The second paragraph hints at them, saying "Importing this module will append site-specific paths to the module search path and add a few builtins" but fails to mention what those builtins are. We should add a brief section listing those added objects, and in the case of help linking to pydoc.

The exact additions are potentially site-specific, but we could add the current default additions as long as they are labelled as such and not as guarantees.

How are they more site specific than everything else in the site module?
