clientmap, clientmedia: code modernization
* use range-based for loops * simplify some tests * various code style fixes * remove debugprint in ClientMap::getBackgroundBrightness, debug code was not intended to be there * remove unused fields in MapDrawControl * use emplace_back instead of push_back when necessary
