- Added workflow updates in order to eliminate
  "modify" as the first transition in a WF

  - Fixed creation of im_biz_object_rel relationship objects
  - Changed semantics of list pages: They now also return
    instances of object sub-types. Example: im_project also
    returns im_ticket and im_timesheet_task objects

  - Added a next-object-id.adp data-source in order to allow the
    GanttEditor to assign task_ids to new tasks. This is necessary
    in order to save the parent/child relationship between tasks

  Added the option to create timesheet tasks with a predefined
  task_id/project_id. This is necessary for the GanttEditor that
  needs to assign task_ids in order to save the parent/child
  relationship between tasks

  - Creating new timesheet_task objects:
    Now creating a unique project_nr if not
    explicitely specified

  Removed the iconCls field for tasks, because that's set
  in the TimesheetTask model

  - Deal with incomplete data if either start- or end-date are not set.
    This is possible in case of tickets and incompletely created
    timesheet_tasks.
    We now set the empty date to the respective other one.

  Fixed quoting to be aligned with specs

  Fixed JSON quoting to deal with \ and " and
  adhere to standards in general

  Fixed error in GanttEditor not showing the task tree
  because of invalid JSON due to a missing value

  Fixed issue that leads to crashes of AOLserver under Windows

  - Changed dependencies to be stored with task information
  - Fixed dependency direction

  Excluding rule_engine_old_value from being returned,
  because the content can be very long

  Now ignoring update requests for a record with id="root",
  which corresponds to the root of the tree.

  Fixing minor errors creating/deleting tasks

  - Working on the CRUD back-end
  - Fixed assignment saving

  Working on tree panel

  Working on TaskTreeGrid columns and custom fields

  Now showing resource assignments behind project bar

  now includes % assignment information per task

  Fixed issues when working with user "Unregistered Visitor" with user_id=0

  - Resolved issue with im_ticket permission query

  Removed unnecessary warning

  - cost-center-tree.json.tcl data-source for cost-center tree
  - "server-side proxy" for loading data from a different Web-
    server. This can be used for loading the open tickets for
    a Web page from www.project-open.net

  Now allowing to DELETE objects if the user has admin_p permissions
  on the object

  Removed debugging code

  Fixed the issue of "Rest Configuration" of Column Configs
  not being deleted because of a missing "id" field

  - Fixed im_timesheet_task_dependency object type

  - Extended the im_sencha_preference to include the URL of the page
  - Fixed sencha-core drop-script

  - Create im_sencha_preference object type
  - Integrated the otype into REST
  - Managed to get Configuration menu more or less working with REST
    back-end
  - Creation, update, delete works
