NAnt - A .NET Build Tool

What I did to reproduce this:
1. Create a solution with a project.
2. Add an NAnt build file to the solution
3. Run NAnt on the build file.

You will receive an error saying something like, "Error checking whether
Solution Items is an enterprise template project"

If you look at the solution file, you'll see a Solution Items that is part
of the projects in the solution. This is a virtual folder that should not
be processed.

I created a patch for this on my system, but I don't know if it's the
optimal solution. I remember looking at some of the code. I think you can
take care of it using regular expressions or a simple if (!Solution Items)
{ // keep going }
