James Sherlock c736a37b5f Fix storyboard example app, Fix example build issue
Summary:
Collection view layout has "user defined runtime attributes" which were left over from the old IG grid layout. I've removed them as we don't use them any more.

Also I couldn't build the project because of the map function in the dependency injection example, so changed that slightly to make it run (tested that and still works)

Issue fixed: #656
Closes https://github.com/Instagram/IGListKit/pull/658
