v1.1.0 Feature Update

IMPORTANT:
Percent encoded slashes (i.e. "%2F") were substituted in the redirect URL. If certain connections with authorization providers fail, you might need to update the redirect URL (see module settings).

Additionally supported authentification providers:

• Dropbox
• Spotify, contributed by @arbor95
• Authentik, configuration with "Generic" provider contributed by @ProjectPatatoe

New Features:

• Connect existing webtrees users with authorization providers
• Disconnect an user from an authorization providers
• Module setting to keep email address synchronized with provider
• Sign in and registration are handled separetely with different menus and views
• Directly register new authorization provider users without showing "Register" page

Other Changes:

• redirect URL: Substituted percent encoded slashes (i.e. "%2F") by characters (i.e."/"), because Dropbox would not accept percent encodings
• Improved debug logs and flash messages

Bugfixes:

• webtrees primary menu not shown in some of the views
• Improved robustness if provider is assigned to an user, but provider is not configured
