MSBuilder.ThisAssembly.Metadata 0.1.1

This package extends MSBuilder.GenerateAssemblyInfo to also generate a static
`ThisAssembly.Metadata` class with the `@(AssemblyAttribute)` attributes that
have `Include="System.Reflection.AssemblyMetadataAttribute"`.

So for an attribute like:

 [assembly: System.Reflection.AssemblyMetadataAttribute("Foo", "Bar")]

You get a corresponding `ThisAssembly.Metadata.Foo` constant with the value `Bar`.

Example:

   <ItemGroup>
     <AssemblyAttribute Include="System.Reflection.AssemblyMetadataAttribute">
       <_Parameter1>Foo</_Parameter1>
       <_Parameter2>Bar</_Parameter2>
     </AssemblyAttribute>
   </ItemGroup>

Generates (C#):

 partial class ThisAssembly
 {
     public static partial class Metadata
     {
         public const string Foo = "Bar";
     }
 }

or (VB):

Namespace Global
 Partial Class ThisAssembly
       Partial Class Metadata
           Public Const Foo = "Bar"
       End Class
   End Class
End Namespace
