First pull request - fixed QR issues.

I re-fixed the issues with the QR reader view controller and sorted everything out with git. I would recommend merging this into your main repo here on Github and cloning it locally. You can do this in the terminal by changing to the directory you want the cloned project to be in and doing "git clone <clone URL>" the clone URL is the same on you used to make the remotes on your end. This will create a new project in the directory in exactly the same state it is in your github repo. There was an issue where you have your images in a separate repository, so they are not going to be a part of the cloned project. You can fix this by dragging and dropping the files into your new (cloned) project and adding them to the project (option-command-a). After this you should commit and push to the Github repo. From now on when I make changes and you merge them into the project via pull requests you will have to do a pull locally in Xcode to update the project locally. You should do this every time there is a change on the project. Let me know if you have any questions. -Ryan
