**Big ass update warning**

* Renamed plugin console message, to send a message to a plugin, use either "plugin <message>", or any unrecognised message will be sent ("plugin" sends explicitly) This replaces the old "script <message>".
* Terrain commands - "terrain <command>" now works again. "Script terrain <command>" does not. Many of the commands have now been reimplemented, eg load-tile. However some have new syntax.
* New console command handler, you can now use things like "terrain help" or "terrain save help". See TerrainModule.cs for an example of how to use the new "Commander" class.
* Commander class - advanced processing of console input and also enables a script API to be generated from registered console commands.
