Added support for terrain map to be serialised to xml(as base64 binary). useful for places that the terrain map is needed in a serialised form. Also could add console commands to save and load from files, which should be faster than .raw files (these load/save commands are not included/implemented)

Add util functions to compress and uncompress strings. 
Fixed a couple of modules so they use SceneCommunicationService rather than directly call functions on the CommsManager.
