Error when using gevent with allow_unsafe_werkzeug

[alethiophile]

Describe the bug
When using gevent and gevent-websocket, if the allow_unsafe_werkzeug argument is passed to the SocketIO constructor, the server fails to start:

To Reproduce
Steps to reproduce the behavior:

1. Install gevent and gevent-websocket
2. Run socketio with the allow_unsafe_werkzeug option
3. note crash

Expected behavior
If the server is going to be using gevent anyway, it should just ignore allow_unsafe_werkzeug, since the werkzeug server never comes into it.

Can I ask you to install the main branch and confirm that the bug is addressed with the above commit? Thanks.

[alethiophile]

Yeah, it works fine now.

Thanks.
