* priority, start/due dates, progress, estimate, spent time roll-up to parent issues
* descendant issues tree displayed on the issue view with context menu support
* issue tree display on the gantt chart
* issue tree copy on project copy
* unlimited nesting

Subtasks can not belong to a different project than the parent task.

Implementation is based on scoped nested sets for fast reads and updates.
