feat: F4.8a the documentation items in model and file, measured against Java's

New oracle DocuRun on Java's JDocuElement. Italic is kept (the model knew
only bold), an item keeps its file's size and font size (Swift's 32 x 24
and 8-72 changed Java's files), an item without a colour is Java's light
grey. Java's new items, colour lists, font sizes and styles, the drag's
smallest sizes and Java's stacking; document commands for the editor.
