Ensure SequenceServer::App uses the same Logger instance throughout.

Wrapping `Logger.new` in `Proc.new` caused a new Logger instance to be returned
on each invocation of `settings.log`.  This is sub-optimal and looses all
customization made to the Logger instance -- log level and log format, during
startup.  Removing the surrounding `Proc.new` ensures the same instance is
returned each time `settings.log` is called.

Bring database_formatter under SequenceServer namespace.

And re-indent the code and strip trailing whitespaces.
