Mono bindings and OBJECT_PATH

[Owen Fraser-Green]

Hi,

I've checked the Mono bindings into the dbus repository now under the
mono directory. There's a brief README and an example directory with a
simple "echo" example. Note the code is still very much alpha quality
and there are some glaring omissions (e.g. signals). 

Is it OK for me to commit the OBJECT_PATH stuff I was talking about last
week? With that in place the Mono bindings are then able to pass objects
by ref.

Cheers,
Owen
