Add localization strings

The Photo Editor SDK displays a number of strings that can be freely changed in the Localizable.strings file of your app. Please, make sure that you've included all the strings with the photoEditor key prefix in your app's Localizable.strings file from the Localized Strings file provided with the sample project to prevent placeholders from showing up in the photo editor's UI.

If you are still seeing placeholders, make sure that the App Language in the Xcode Scheme Options is set to English as this is the only language supported by this demo app.
