* Updating libsecondlife.dll to the latest version with a working LayerData function
* Reformatting some source files * Adding a try/catch sanity check around a phoning home check to osgrid.org * Updating the MSVC project file * Converted LayerData generation to use the functions built in to libsecondlife * Removing unused BitPack.cs and TerrainDecoder.cs files * Added a basic terrain generator (hills algorithm)adam
