XNA Game Studio 3.0 beta updates

The following table lists all of the API changes between 2.0 and 3.0. There are changes to internal structs and other things but I'm not listing them here unless it seemd particularly interesting - the public interface changes are quite enough to digest. The changes are based on the Windows versions of the assemblies. Maybe I will compare the others at some point.

I know its not very readable... I will tidy it up a little later on
