submitting hours for confirmation

   Allows removal of configuration objects no wf_case exists for
   Useful in particular when testing WF's

  It's replaced by the confirmation links in the calendar

- replaces ad_export_vars with export_vars

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

  OpenACS 5.9 does not allow anymore single percentages
  without enclosing double quotes such as: width=100%
  Instead, we have to write now: width="100%".

  Not starting first transaction anymore, unless it's "Modify"

  Fixed rounding issue

  if uses modify already submitted hours

  Fixed(?) Issue with missing default values(?)

  Added an "unsubmitted-hours" report showing who didn't
  yet submit hours

  Added feature to send our reminder emails to users with unsubmitted
  hours

  timesheet confirmation_objects

  Showing conf objects now with status

  Fixed English and German translation
