[PATCH 09/10] org-taskjuggler: allow reports definition from within the org file

[Yann Hodique <yann.hodique@gmail.com>]

This renders reports production much more flexible.

* org-taskjuggler.el (org-export-taskjuggler-report-tag): new custom variable
 (org-export-taskjuggler-valid-report-attributes): new custom variable
 (org-export-as-taskjuggler): compute reports
 (org-taskjuggler-open-report): generate report from org item
 (org-taskjuggler-insert-reports): insert default reports only if no explicit one is defined
