* ruby scripts were refactored
* environment values are now exposed to Info.plist via xcconfig file
* environment values became available in Build Settings
* cocoapods integration fixed - no need to add custom code to Podfile!
(as suggested in this PR: https://github.com/luggit/react-native-config/pull/329)
When react-native is installed using cocoapods xcode cannot find react headers for react-native-config. This PR adds to HEADER_SEARCH_PATHS to look at header files in the Pods.
Since Cocoapods does not allow build scripts it's still a good idea to link react-native-config with react-native link and add support for projects that do use react native via cocoapods
