This replaces a dynamically allocated array of bool by std::vector<char>. 1) This makes the code shorter and less error prone, because memory management has not to be done by hand. 2) It fixes a bug in the old code: memset(checkState, false, list.count()) is wrong, because bool is not guaranteed to be the same size as char! Two notes: 1) QMap<>, QVector<>, etc. are used numerous times in the code, so this doesn't introduce a new C++ concept. Here, the std:: version is used, because there is no need for reference counting, COW semantics, etc. 2) std::vector<char> is used instead of std::vector<bool>, because the latter does a pessimization where a bitfield is used!
