Count of alternate message values was limited to 1 value. Now it is
possible to add any count of message values.
directKey and directKeyAlt were removed from struct type 'button_label_cc'
and directKeys was added as container for possible message values.
Some methods of CComponentsFooter had to be adapted for that.
