- updated chart header of care measures widget: now it is obvious that
triage classification of all patients is displayed

- implementation of the qualitative kpi6b 'Percentage of correct
supplied patients' (v1) which shows the ratio
#correct_supplied_patients/#all_patients as parcentage. A patient is
supplied correctly, if all necessary care measures have been applied by
a responder; wheather a measure is necessary or not, is determined by
the pattern of injury, that is assigned to a patient.
