New Radiality version and sample

I did some more work on Radiality and actually made a release, there are no new features (that's essentially because I can't come up with any), just some code cleanup, mostly to use the new C# 3.0 stuff. There is also a fairly complete XNA sample project that should give you a pretty good idea how to use it.

Radiality is on CodePlex

As promised, here it is, Radiality is now on CodePlex, get it here http://www.codeplex.com/radiality
