* Fix for Scene.Inventory.cs - It assumes every entity at startup is a SceneObjectGroup. (Actually, this shouldn't have compiled[!] without a warning.)
* Fix for LandManager at startup - it assumes there's a land channel when perhaps there isnt. (Bug that needs another refactor to fix. [Mike - I've assigned a ticket to you about this])
* Added shell of new Python scripting engine. Similar in design to the one used by Rex, but will be structured at a region rather than object level, also is a region module.
