set date parsing to non-lenient, added tests for correct and incorrect date strings, expect NULL for incorrect date strings based on current logic
manually set converter for date fields allowing us to customise parse behaviour before passing to validation
Parsing of dd-MM-yyyy format dates now done using CommonUtils.parseUKDate(), UI elements based on RadarDateValidator now use this and validate with existing RadarDateValidator (currently checks if year < 1000)
