- added support for loading DeepBSP's V4 nodes.
- disabled writing the nodes with the dumpmap command. ZDoom doesn't need the nodes to load a map and this only worked if the original map had standard nodes but trying to write out nodes loaded from any other format would have caused broken data. SVN r2285 (trunk)
