The iOS and OS X SDKs now share a non-UI test bundle. Moved the iOS UI test bundle into a uitest/ subdirectory and moved the OS X SDK tests into the darwin/ subdirectory.
Upgraded KIF to v3.4.2.
ios.xcodeproj is an ordinary Xcode project with ordinary Xcode targets for iosapp and ios-bench, all contained in an ordinary Xcode workspace that happens to also reference the gyp-generated platform.xcodeproj. The iosapp target links to and embeds Mapbox.framework, which is a product of the gyp-generated platform.xcodeproj. ios-tests.xcodeproj is also in the workspace, enabling simultaneous debugging of KIF tests, the SDK, and core code.
Moved storyboards into Base.lproj and image assets into an asset catalog. Removed iOS 6 assets from the iosapp asset catalog. Moved the original ios-bench application icon SVG into a non-project location.
Removed app/Settings.bundle, which is identical to framework/Settings.bundle.
Removed a broken reference to an unused header from the ios-tests project.
When a map view was smaller than the entire viewport, negative content insets would be applied. Negative content insets would only be valid if the map view extended outside of its frame, which cannot happen.
Fixes#4440.
