Should be able to access remote objects' properties via C# properties

[gburt]

The flip side of Issue 17 is being able to access remote objects' properties (that are exposed via org.freedesktop.DBus.Properties) without having to explicitly use that interface, but rather via C# properties.

Hi, this feature would definitely be desirable!

I had a hack around a bit and managed to make Get work by doing this: http://pastebin.com/5B1vk8DW against the 0.7 tag. I think Set could be done similarly, but I'm not sure whether it's an ideal approach?

EDIT: @garuma, I've done a bit more work on this and made a pull request, #37, so the above pastebin diff can be ignored, the version in the pull request is quite a lot cleaner.
