+ Fix `top-margin` in the choose activity
+ Rename `ViewPager` files for Settings to contain the string 'Settings'
+ Rename `firstStartup` to `Tutorial`
+ Remove unused library imports in `SettingsActivity.kt`
Split up the `SettingsActivity` into the smaller Fragments, Rename many
ids... overall cleaner code.
