- idna.encode does not encode upper-case letters,
so .lower() has to be called on value not on result
- split email-address on '@' only once
- converted '*'.format(*) to f-strings
- added docstrings
- removed from_dict method
- code cleanup/style (list concat, exceptions, return&else, line-length)
- added TODO comments on possible future changes
- revived original config-update function for backwards compability
- renamed config-dump to config-export to be in line with config-import
- converted '*'.format(*) to f-strings
- converted string-concatenation to f-strings
renamed single letter variables (m => match)
renamed classmethod arguments to cls (model)
removed shadowing of variables (hash, context)
shortened unneeded lambda functions (id)
converted type ... is to isinstance(...)
removed unneded imports (flask)
Updated ConfigManager to only modify app.config and not replace it.
Swagger does not play well, when app.config is not a real dict and
it is not necessary to keep ConfigManager around after init.
Also added "API" flag to config (default: disabled).
