"There are security restrictions on this article" is user-hostile language.

We need to create a mediawiki extension: "Patch"

Patch will encapsulate our current mediawiki extension which enables author-triggered lockdown of pages, called LetMeCheckMyNotesAndFixThis

What "Patch" Does

User Experience: A permitted user/author sees
"edit/patch"
at the top of the page. Both the "edit" and "patch" links work.

A non-permitted user gets a sees
"edit/patch"
at the top of the page. "patch" works. "edit" redirects to patch with a _friendly_ explanation.

The "patch" button on Extruder creates Extruder/Patch137 if there are already 136 patches.

The "patch" button on Extruder/Patch3 creates Extruder/Patch141 if there are already 140 patches.
