v3.7

✨ Added

• Casting support for update_values of a model, similar to laravel's casts, e.g.: uploaded_at:date. Supports.
  bool, int, float, date, string, trim (a trimmed string), none (to prevent from casting empty values to NULL).
• Queue daemon, which can run the queue reliably twice each minute, similar to the cron daemon.
• New method to generate a random filename with 25 characters: C::Storage()->getRandomFilename().
• New method C::getAllAppModules() to only get app-related loaded modules like the App module, no kernel modules.
• Slugifying is improved and can now create safe filenames via C::Formatter()->slugify($text, true).
• Simple method to download files via C::Http()->download($url).
• The model cache can easily be cleared via $model->clearModelCache() or to clear the full cache of all entities
  of this model, use ModelClass::clearModelsCache().

🔧 Changed

• Redis usage in the whole system is now optional, works fine without redis at all [#40].
• The environment config file app/app.env is now a proper ini-file.
  Kept legacy support but preferred syntax is now e.g. ENVIRONMENT=Prod.
• The cache clear command is now available via bob c:clr to make calling it more efficient.
• Database migrations are now only run on app-related modules, no kernel modules, since they have no migrations.
• The keys for the authentication token on requests can now be adjusted via config.
• Improve backup + restore methods for models. Now with an optimized handling of large datasets and using NDJSON.
• Updated dependency packages to their latest versions, replace maximebf/debugbar with php-debugbar.

🔥 Removed

• Global is_json function, replaced by PHP's native json_validate
• Global is_serialized function, is unnecessary nowadays since this would duplicate running unserialize.
