#4 Make the code work in .NET framework 2.0 and higher

- Removed BinaryVersion.Core. Rather than having this a core library
that could be used by other projects targeting particular framework
versions, I made the actual BinaryVersion.Handler compatible with .NET
framework 2.0. The drawback is that I can't use LINQ and other nice
features, but the benefit is that it immediately works in older websites
running on .NET 2.0
- Updated version to 0.0.2.0
