This version of the Gantt chart supports nested charts. So Projects,
Versions, and Issues will be nested underneath their parents correctly.
Additional features:
* Move all Gantt code to Redmine::Helpers::Gantt class instead of having it in
the Gantt class, controller, and view
* Recursive and nest sub-projects
* Recursive and nest versions
* Recursive and nest issues
* Draw a line showing when a Project is active and it's progress
* Draw a line showing when a Version is active and it's progress
* Show a version's % complete
* Change the color of Projects, Versions, and Issues if they are late or
behind schedule
* Added Project#start_date and #due_date
* Added Project#completed_percent
* Use a mini-gravatar on the Gantt chart
* Added tests for the Gantt rendering

* priority, start/due dates, progress, estimate, spent time roll-up to parent issues

* 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.
