Remove hard-coded file routes.

Add:
        app.py
                -Remove hard-coded routes for files in the application's "root"
                (`static/`) directory; redefined Flask's `static_url_path`
                accordingly. Files can now be directly accessed by URL.

        bitshift/assets.py
                -Remove the `static/` prepended to all resource paths.
