title: Cordova manifest capability for windows platform
body: <p>We are developing an Window Store App with Cordova and trying to authenticate user against Windows Serve AD. There is a capability "Enterprise Authentication" need to be set on package.windows.appxmanifest. We can do it direct from VS2015 RC, however this file will be overwritten every time Cordova build.<br>
  We've tried to following this:
  <a href="https://stackoverflow.com/questions/28960806/windows-phone-capabilities-with-cordova">Windows Phone Capabilities with Cordova</a> and this: <a href="https://stackoverflow.com/questions/25930856/adding-privatenetworkclientserver-capability-to-windows-8-cordova-application">Adding privateNetworkClientServer capability to Windows 8 Cordova Application</a>
  but could not success.
  Did we miss something or somebody point us to the right direction? Cordova document is not help much.
  Thank you in advance.
  Configuration:
  Windows Store App
  Windows 8.1
  Cordova 5.1.1</p>
