SCH_LEGACY_PLUGIN::loadHierarchy() uses a stack to maintain sheet paths 

Path keeping stack copes well with paths pointing outside the project
directory (e.g. "../path"). The so far used wxFileName::GetDirCount() and
wxFileName::RemoveLastDir() remove too many directories, as ".." is also
counted as a directory.
