title: Add NuGet package without its dependencies
body: <p>I am sure many of us have run into this issue and somehow i am having problems getting resolution anywhere. </p>
  
  <p>I have a shared library (Common.Infrastructure.dll) across many projects and I am using TeamCity built in NuGet Server to host this library. This library internally relies on NuGet packages such as Fluent Nhibernate, Log4net, StructureMap, etc). </p>
  
  <p>Quite simply, doing a "Install-Package Common.Infrastructure" in a project that needs this shared dependency also adds Fluent NHibernate, log4net, SM and so on) as "references" to the project. I am not going to use these dependencies of Common.Infrastructure directly, but would obviously need them in the output (bin/debug) folder eventually. </p>
  
  <p>Is there a way to not have these dependencies referenced with built in nuget (nuspec) support?</p>
