Allow solution templates to specify project references

Current solution templates that create multiple projects cannot create
project references between those projects because the ProjectGUID is not
available to templates

This actually works for my solution templates that create multiple projects. I use a declaration like this:

<Project ..... >
    ...
    <ProjectItems>
        <ProjectReference  Include="..\${SolutionName}.Common.Interfaces\${SolutionName}.Common.Interfaces.csproj" />
        <ProjectReference Include="..\${SolutionName}.Common.Business.Model\${SolutionName}.Common.Business.Model.csproj" />
    </ProjectItems>
    ...
</Project>
