Updated CardIOVideoStream's delegate to be a UIResponder to fix Xcode 8 compiler error

[reidmain]

Detailed explanation of this change is in issue #69

[reidmain]

I can't figure out how to run unit tests for the project. If I select the UnitTest scheme and try to build it I immediately get the build error CodeSign error: code signing is required for product type 'OCUnit Test Bundle' in SDK 'iOS 9.3'.

Is there something specific that needs to be configured for the unit tests?

LGTM. Leaving to someone else to merge. Don't sweat the tests. For this trivial a change in a heavily used code path, if it compiles and basic functionality works, I'd say it's good.

[reidmain]

Cool. I ran the example app on device and was able to recognize a credit card with no issues.

Is there someone we can ping who can merge this PR?

@reidmain Looks good to me. Thanks for the PR and sorry for the delay.

[reidmain]

@bluk no worries. Xcode 8 isn't even GM yet so I understand. If I experience any more issues while trying to integrate this into a Swift 2.3 app I'll open up some more.
