Changed Label to be able to setText(...) and getText()
First Version of ArrowSelectionScreenPreSet. Right now ArrowSelection is used, however ArrowSelection is generally ready to be used (without warnings and controls). In ArrowHelper the two Methods ArrowHelper.instanceArrow(String selectedArrowName) and ArrowHelper.instanceArrow(int selectedArrowIndex) were added to return an Arrow-Object directly instead of using ArrowHelper.reformArrow(...).newInstance() which need to be surrounded by try & catch.
