title: Change Octopack nuget version numbers to teamcity's build number
body: <p>I Created an Octopack nuget package of an asp.net mvc website using team-city. 
  I also added build parameters i.e  for package version numbers to use  team-city's  build number <code>%build.number%</code> and not the default as in AssemblyInfo.cs However my package numbers still come up as 1.0.0.0 regardless of the build parameters that I set. </p>
  
  <p>I have tried  to use the .* in AssemblyInfo.cs which  auto generates version numbers but I would like to use  team-city's build  numbers as I have defined  them . </p>
  
  <p>Is there something else I'm missing? </p>
