Closes #90

Fixes #79

per comments from @eileen here https://github.com/civicrm/api4/issues/14#issuecomment-278860730

fixes #84

real content

that URL hacking works

"Request a review" instead of "request a request".

(I looked at the content in this file to make sure there's nothing in it
that can't be found elsewhere. All content already exists in the wiki
and thus is moved over as part of auto migration for hooks.)

(the migration is easy to re-run if needed)

(files still need to be moved around)
