Changing the selected metrics no longer restarts the entire application, but only updates the metrics panels in the viewer frame (see updateSelectedMetrics).
ViewerFrame: added method parseSelectedMetricsData.
ViewerFrame: removed qcParamNames and selectedMetrics (could be done with selectedMetricsKeys).
ViewerFrame: use logger instead of println, added FONT and FONT_NAME constants.
ChooseMetricsForm: split the constructor in smaller parts.
ChooseMetricsForm: added method createMetricsPanel for two similar pieces of code.
ChooseMetricsForm: introduced some constants and added more documentation.
SortedListModel: items are always strings and removed unused methods.
MetricsParser: moved getMetricsListing.
Fixed small issues: changed names, final parameters/variables, etc.
