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.
