iOS Support

Create a version of Prism for iOS.

Considerations

Apple will not allow developers to programatically change the device's wallpaper. Therefore, my proposed solution for iOS is to simply allow the user to save each wallpaper. They can then go into their Photos app and set the wallpaper themselves.

So we can simply remove the set wallpaper button, there is already a download button, and therefore simply the users can then proceed to set the wallpaper themselves. We can simply show a toast message when the download is completed to set wallpaper using Gallery.
