Compile Time Changes

class BlockSpace

A new function for invalidating BlockSpace ItemTags has been added.

• Overidden from the super classes implementation
• Calls block.?updateOwners(..) after the invalidation has been done

/**
 * Invalidate all item tags in BSP.
 */
public void invalidateItemTags(dirty2D flag2D=dirty2D.all) {
	super(..);
	block.?updateOwners(recursive=false, excludedSpace=this, flag2D=flag2D, flag3D=dirty3D.none);
}
