ResponseWriter Interface to support Hijack() to allow websocket

[JeffMerlet]

In order to support websocket with violetear, using something like Gorilla websocket, violetear's ResponseWriter implementation would need to support the Hijack() function. The Gin project added that feature for the same reason; see gin-gonic/gin@4a24c47

Thanks!

Hi, @JeffMerlet to support all interfaces don't use LogRequests by default is disabled, or set it to false:

 router := violetear.New()
 router.LogRequests = false

Please give a try and let me know if works.

I can confirm that when setting router.LogRequests to false I'm able to connect to the websocket without any problem; and was even able to retrieve a named param used on the web socket URL without any problem.

I will close the issue now. But I would suggest to add some documentation and/or simple example about it as it could be helpful for others. Thanks and great job on the router!
