0.8.2

Minor release that sets the SDK version not just in the Cocoapods specfile, but also in OptableSDK.xcodeproj/project.pbxproj via MARKETING_VERSION (which in turn is set as CFBundleShortVersionString in Source/Info.plist and is used by the OptableSDK when sending its version number to the sandbox for debugging purposes). This means that developers installing the SDK via e.g., Carthage instead of Cocoapods can now expect that their true SDK version is passed along to their sandbox, instead of the default 1.0 which was the case prior to this release.
