[O] [PATCH 07/10] org-taskjuggler: make project umbrella task optional

[Yann Hodique]

introduce `org-export-taskjuggler-keep-project-as-task' as a flag to toggle
the behavior. Keep old behavior as default.

* org-taskjuggler.el (org-export-taskjuggler-keep-project-as-task): new custom 
variable
 (org-export-as-taskjuggler): optionally drop the topmost "task" (project)
 (org-taskjuggler-assign-task-ids): adapt path computation by optionally 
dropping the topmost component (project)
