Returns a string that represents a join of a list of strings with a localized separator. This function corresponds
to QLocale::createSeparatedList which was introduced in Qt 4.8 and implements the algorithm from
http://www.unicode.org/reports/tr35/#ListPatterns
NOTE: translate() can change the format based on language styling (ex: Finnish not using "{} and {}" rather than
english style "{} , and {}").
