Release v4.22.0

The structured properties of the PrimeReact controls are now described by their fields, so a host edits them without JSON text or an "undescribed property" diagnostic.

Added

• PropertyEditorKind (stringList, numberList, stringOrList, scalar, stringMap) names the editor for a value that has no fields to describe: a list of words or numbers, a word-or-list, a scalar, a record under the author's own names.
• CollectionItemDescriptor.positional lets a collection of authored data (chart datasets, tree nodes, columns) hold records without an id; items are told apart by position.

Changed

• chart describes data (labels, datasets), options and style; treeTable describes columns, items (nodes down four levels, a node's data a map) and selection; dataScroller items and multiStateCheckbox options, icons and value are described. Structured values stay bindable to a data context, a query result or a component property.
