Added default config => switch to SQLite

Added default '.env' config file. I'm keeping the '.env.example' in the repository, but an easier setup process a default configuration will from now on be included in the repository.

I'm switching from MySQL to SQLite for the same reason mentioned above. By adding the MySQL database setting from '.env.example' to the '.env' config, MySQL can still be used as the database.

.env
