RMZeroFour c3c7b48fa9 .NET Bindings: Native bridge for .NET
This patch includes all marshalling and proxy handling code on the
.NET side as well as the native side needed for a fully functional
UNO bridge.

It also includes some changes and corrections to net_basetypes and
netmaker needed for the bridge to work properly.

It also includes the FirstUnoContact example in C# as demonstration.
