Begining major rework of Asset/Inventory code. Doing a lot of refectoing. What's in here so far?

+ Inventory, Asset and Image managers are now directly apart of the SecondLife class
+ Root Inventory folder has been added to MainAvatar and is set upon login
+ Inventory is no longer downloaded all at once, you have to request the download of individual folders
+ Folder downloading is available Asynchronously, and returns a object that has a ManualResetEvent that you can use to optionally block with
+ The code for AssetManager has been reworked some in prep for allowing Wearables to be Saved/Loaded to/from disk, and for creating new wearables.
