* 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
Defining subtasks requires the new permission 'Manage subtasks'.
Subtasks can not belong to a different project than the parent task.
Implementation is based on scoped nested sets for fast reads and updates.

* closing a issue will close its duplicates
* closing a duplicate won't close the main issue

* relates to: do nothing special. Just to know that the 2 issues are related...
* duplicates: will close the related issue with the same status when closing the issue (not implemented yet)
* blocks: will require to close the blocking issue before closing the blocked issue (not implemented yet)
* precedes (end to start relation): start date of the related issue depends on the due date of the preceding issue (implemented). A delay can be set so that the related issue can only start n days after the end of the preceding issue. When setting dates for an issue, dates of all downstream issues are set according to these relations.
To set a relation, the 2 issues have to belong to the same project (may change in the future). So if an issue is moved to another project, all its relations are removed.
Circular dependencies are checked when creating a relation.
