* Remove superfluous method arguments in method references
* Use 'Self' for internal static access
* Convert static to instance field in singleton class
* Remove class name prefix in references to local methods
* Remove nested frameworks in all extensions and frameworks
* Add notification action to copy OTP or just inform about the copied OTP
The notification either shows the current OTP which can be copied by a notification action or it shows just a hint to inform about the copied OTP. This depends on the new option "autoCopyOTP".
* Extract method
* Set type and style one-time
* Allow to do something with a password after providing it in the extension
* Make fields non-nil
* Show OTP in notification after providing a password through extension
* Do not present lock view in 'viewDidLoad' since this might be too early for an extension ("Not running foreground").
* Instead, show it for actions requiring authentication, e.g. showing the password list or providing a password, or only in 'viewDidAppear'.
* Refactor and lazily load other view controllers and data.
* Let credential providing view controllers decide when to hide themselves.
Previously, the Pass extensions (for autofill and for the sharing sheet)
didn't see their strings being localised. This means that in some cases,
English was the only thing shown and in others strings would look like
`#EnterPasscode#` on the passcode lock screen. This was because their
build phases didn't reference the localised string files in the `Copy
Bundle Resources` phase.
This change ensures these localisation files are copied and thus the
extensions are now localised for both English and German (so far).
