Make NuGet a first class citizen.

Currently the packages folder is checked into the ReactiveUI repository and not all libraries are coming from NuGet.

I believe this was done because of Xamarin, but we should definitely switch when Xamarin supports NuGet.

I have not checked if it was already supported or not :). At least we now have an issue to track this.

I'd really like @paulcbetts his opinion on this.

We can probably do this now - before, we had a lot of churn in Rx and other libraries, not everything was available in NuGet, etc etc. There was a ton of reasons to keep everything in ext, but none of them are really true anymore. Even NuGet added a feature for us where packages.config couldn't be used if you kept all of your csproj files in the same folder.

So what I'm saying is, 👍 on NuGet'ing everything :)

This is a good idea, but probably not blocking RxUI 6.x release, we can do this whenever

I'll hold of on this until #590 and #552 are done.
