* Adding generic HttpServer to OpenMetaverse.Capabilites
* LoginResponseData can now serialize to XmlRpc * Adding new Simian project, ultra-lightweight simulator for testing and development * Shuffling OpenMetaverse.Capabilities around a bit in preparation for CAPS server implementation git-svn-id: http://libopenmetaverse.googlecode.com/svn/trunk@2094 52acb1d6-8a22-11de-b505-999d5b087335
