Subject: * Creates Util.UTF8 and switches some references of Encoding.UTF8 to
 Util.UTF8 (not all references were switched since not all OpenSim libraries
 reference OpenSim.Framework) * Shrinks the largest in-memory object, the
 LLRAW.HeightmapLookupValue struct (only used for exporting to LLRAW terrain
 files), to the minimum possible size. This seems to have the odd side effect
 of cutting the size of the two double[256,256] terrain objects in half.
 Possibly an alignment optimization?
