Adding references for Razor translations.

You can add references to the Razor engine by specifying them in the Smartsite.config file:

<configuration>
  <runtime>
    <razor>
      <assemblies>
        <add assembly="System.Xml.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
      </assemblies>
    </razor>
  </runtime>
</configuration>
