Sockets.route should preserve handler docstrings/annotations/etc.

[achimnol]

The original Flask framework uses functools.update_wrapper() for handler registration methods such as add_url_rule() so that docstrings, annotations, and other metadata of the app.route()-wrapped function becomes equivalent to those of the original user-defined handler function. To be consistent, Sockets.route() or Sockets.add_url_rule() method should do this as well.

Cool, @achimnol have you got a pull request?

Ooops, I pointed the wrong stuff. Sockets.route() is working as expected, since the decorator just returns f as-is and only calls add_url_rule() as a side-effect. The root cause of my problem was a missing entry in __all__. Sorry for bothering. 😞 (We should not write codes when sleepy..... 😪)
