Before this change, next() was the only way to advance the iterator, whether the caller was ultimately interested in just the filePath() (good) or not (bad luck, had to call .fileInfo()). Add a new function, nextFileInfo(), with returns fileInfo() instead. Incidentally, the returned object has already been constructed as part of advance()ing the iterator, so the new function is faster than next() even if the result is ignored, because we're not calculating a QString result the caller may not be interested in. Use the new function around the code. Fix a couple of cases of next(); fileInfo().filePath() (just use next()'s return value) as a drive-by. [ChangeLog][QtCore][QDirIterator] Added nextFileInfo(), which is like next(), but returns fileInfo() instead of filePath().
