engage siteAdapters, err details to console

Here we use LINEUP to diagram pages from both http and https sites. With this now working we can consider how other algorithmic markup can see deeper into the federation.

Remove MEHAFFY & diagram()
Add Redirect argument to DOT keyword.
Add new about pages including MEHAFFY replacement.

I've changed the redirect syntax to be more readable and unambiguous at the same time by signaling redirect with DOT FROM.

I had overloaded the DOT keyword in a way that DOT graph could have two meanings. At first I didn't consider this a serious problem because a page named Graph would have to contain a Graphviz plugin before the second meaning would be unavailable. But why be so clever.

As discussed, this looks good for publishing a next tagged version from this branch.

This fetch fails on ghost page.

Debugging with "Pause on Exception" we find this code in jQuery-migrate that is trying to catch this error but not getting the null that it expected.

Lineup Diagram once again readily retrieved by searching for it. Here is my rather complicated test case that had be caught in an edit-publish-debug loop.

[WardCunningham]

We now accept DOT FROM with or without a \n.
We report slightly better error messages when the redirect doesn't work.

[WardCunningham]

Add widely useful Lineup Diagram to about pages.

[WardCunningham]

We now include a brief enumeration of RegExp Metacharacters which is cited in the More About Algorithmic Markup page. This would otherwise be a broken link on most sites.

👍 This looks good to me. I offer one suggestion for logging an error and one reminder after we've merged this PR

[paul90]

Looks good. I've added the suggested error message on the get rather than swallowing the error.
