After I implemented the initial detection, I realized that the supported release information had to live outside of the `detect_installer` capability since supported distributions are release specific. In the medium term I'm planning on passing in a `PEBuild::Release::Instance` object to the `detect_installer` capability and using that to work out if the version of PE supports the given distribution.

In the short term, I would just skip this code entirely. My understanding is that this will just work on any version of Windows, and it'll just explode on Windows 2003 for now, right?
