[FEATURE] Custom properties to specify the Id of a resource (using WithId)
[FEATURE] New way to set up Saule: use the extension method ConfigureJsonApi instead of manually adding the JsonApiMediaTypeFormatter.

[BUGFIX] Saule now supports recursive object graphs
[BUGFIX] Saule can now be installed in .NET 4.5 projects
[BUGFIX] Iconsistency between top-level self link and generated urls. If you don't specify an url path builder, the path namespace is now automatically guessed for you.
