Subject: * Continued work on the new LLUDP implementation. Appears to be
 functioning, although not everything is reimplemented yet * Replaced logic in
 ThreadTracker with a call to System.Diagnostics that does the same thing *
 Added Util.StringToBytes256() and Util.StringToBytes1024() to clamp output at
 byte[256] and byte[1024], respectively * Fixed formatting for a
 MySQLAssetData error logging line
