Added a new ifabric Make target for packaging up a static framework similar to the one released as 3.0.1. Place artwork and certificate assets inside Mapbox.bundle inside Mapbox.framework. Link SystemConfiguration in the umbrella header.
Distinguish between the framework bundle and the resources bundle. For the dynamic frameworks and embedded static frameworks, the two are the same; for the non-embedded static framework, the latter resides inside the former.
This file was originally added on the release-ios-v3.1.0 branch, before #3913 merged ios/ into platform/ios/. When the release branch was merged back into master in 17f44d7bd9, the file was left in the old ios/ directory.
