From 258e62679aca6fa74a20a5275cb0f172402352e8 Mon Sep 17 00:00:00 2001
From: Adam Frisby
Date: Fri, 20 Apr 2007 05:39:01 +0000
Subject: Console: * Reorganised and added default handlers to main functions *
 Removed "regenerate" command, use "terrain regenerate" instead. * Added new
 "terrain seed" command to set the random seed * Added new "terrain load"
 command to load a terrain from disk * Added new "terrain save" command to
 save a terrain to disk Terrain: * Added new export and import functions for
 some common formats * Added new setSeed function to allow customising the
 random seed
