Merge pull request #3 from luquantan/feature/LQApplicationSettings

Feature/lq application settings
Initial commit of new branch feature/LQRecentPhotosTVC
Created LQRecentPhotosTVC and added new TableViewController to main storyboard.
Fixed "data is Null" warning from loadRecentPhotos in LQApplicationSettings.
Changed getter of recentPhotos to always give the latest version from recentPhotos.
Hooked LQRecentPhotosTVC to an ImageViewController.
Made some additions to display recentPhotosTableView properly.
Initial Commit of feature/iPadStoryboard.
Disable size classes. Added new iPadStoryboard.storyboard. Added SpiltViewController in interface builder.
Added TopPlacesSplitVC.
Added didSelectRowAtIndexPath for the iPad splitViewController. Fixed ActivityIndicator to only show while loading photos
Fixed activityIndicator to hide when stopped. Also, added savePhoto helper method in TopPlacesPhotoTVC
Made ImageViewController a UISplitViewControllerDelegate to get image from MasterVC.
Embbeded ImageViewController indside a NaviationController. This allow me to show the barbuttonitem.
However, this prevented TopPlacesPhotosTVC from sending any information to the detailVC, preventing any image from being shown.
The ImageViewController and the TopPlacesPhotoTVC(detail and master) is now connected.
Previously, the master and detail were connected via an unconventional method.
In this iteration, I used NSnotifications to send the information.
