Change the app label of the old Gallery app
In recent Android versions, the Gallery2 app is used. Due to #705, Replicant still uses the older Gallery app because the Gallery2 app doesn't work with the Android software renderer.
The Gallery app has the label Camera which is confusing. Users expect the gallery app to be named Gallery when they browse the apps settings. This naming scheme is also conflicting with the actual camera app as there are two apps displayed in the apps settings that both have the name Camera but different icons.
The label strings of all languages need to be changed.
