Implement Windows version in C# (again)

• Solve the library load path problem
• Sign my program/DLL so VirtualBox trusts it (hopefully)
• Either pass the screen pointer to Java or process it in C# (latter requires the converter methods to be copied over)

I have compiled the VBox MSCOM library, but haven't tested it yet. It may be feasible to make it all in Java.
