Version heading bumped in both layouts, and the tagline under it now
points at the CSS editor instead of ECHO — the banner beside it is
advertising the editor, so the two now say the same thing.
Changelog entry is written for the people who hit this: they saw the
dingus error every time and had no way to know it was not their fault.
It says what happened in their terms and tells them to try again.
README's version log gets the matching line.
