- Enabled deletion of dependencies from the PropertyPanel

- Now showing and converting lags according to the lag format
- Extended im_timesheet_task_dependencies by diff_format_id
  and created  categories for representing lag formats
- Fixed saving and loading dependencies in REST
  /intranet-rest-data-source-procs.tcl and
  project-task-tree.json.tcl
