Adds support for retrieving schedule chart items from Gantt chart components.
Features
- Added drag completing events on 'DragThumbTask' (when used to support vertical drag operations, i.e. hierarchical moving), 'DragDependencyThumb', and 'DragAssignmentThumb' classes. This allows developers to optionally cancel the operations (or, upon dragging new dependency lines, to initialize 'DependencyType') in certain conditions.
- Added support for retrieving schedule chart items with dependency links from Gantt chart components.
