Refactoring to not better use Flask, only when needed: - command-line utility is using plain `argparse`. - no Flask app created unless we want to run a server. - split all commands into sub-modules. - do more initialization stuff in the `WikiParameters`. - make `Wiki` init as cheap as possible. - one `Wiki` instance now created per request.
