Sheet sets: Place on Sheet, sheet view menus, block lists, missing status, field refresh

Model Views lists named model views and places them on the current sheet
(xref, viewport, paper-space named view, view label with navigation
fields, sheet view record); sheet view rows get Display, Rename & Renumber
View, Set category, Place Callout Block and Place View Label Block; the
View Category dialog's Add Blocks opens List of Blocks / Select Block; a
sheet whose relative path is gone shows missing; sheet set fields store
their values when a set changes; named views keep their centre relative to
the target. Codec pin moves to the revision with these field helpers.
