The plugin is not respecting the configurations

[lucabartoletti]

If in the podfile I have

pod 'something', :configurations => ['Debug', 'Adhoc']

The plugin seems to not consider the configuration and apply the framework to all configurations.

I also notice that if the pod contains a static lib, like for example the Stripe pod does, than you end up getting linking errors for the configuration where the pod should not be included

I would like to help and open a pull request but I don't know where to start with ruby and cocoapods plugin development
