Maps: Stored non-entity objects in XML instead of PMP, for easier manual editing. Updated existing maps to newest format, so that they can still work. Added undocumented _rewriteMaps() JS function. Also renamed _mem to vmem, and reclassified its undocumentedness as unintentional, since it's reasonably useful. Loader: added NonprogressiveLoad function, for ScEd/_rewriteMaps/etc which don't care about progressiveness. main.cpp: re-enabled vfs_display, since it doesn't crash now Vector3D: stopped warning This was SVN commit r2078.
