1.1.2

Fixed, where the documentation could not be followed

The Document accessibility fieldtype is selectable. It shipped hidden from
the field picker, so the install the documentation describes could not be
completed: it says to add a field of type "Document accessibility" to the asset
blueprint, and that option was not there. The status column could only be turned
on by editing YAML by hand.

The fieldtype now carries a title, an icon and a category. It stays out of a
form's field picker, where it has no meaning.

Found by installing on a real site and following the instructions as written.
Upgrading re-checks nothing.
