Merge PR #1574 from ramox81/codex/attdef-parity: ATTDEF dialog, -ATTDEF, tag display, Properties and Block Definition ribbon

Conflicts with #1573: the locale files and the catalog take both PRs'
entries (one "Insertion Point" mapping kept); the Home and Insert Block
panels take #1574's layout with #1573's Insert Block gallery.
