Introduce QDir::isEmpty()
A directory is empty when it doesn't contain files or folders. We can exploit QDirIterator::hasNext() to check whether this is the case. This is efficient since it doesn't list the whole folder (in the non-empty case). Test cases are added for both the empty and non-empty cases.
