Switch to debug view

[master0v]

need a working example of how to switch to debug view. With step-by-step instructions. I've spend hours trying to configure it and ga.send(events, validation_hit=True) just doesn't work.

validation_hit seems to be using the /debug view which only returns a response with the errors your event could have, this isn't obvious and I had to go look it up in the code. Still, I have the same problem I tried using the debug view and I couldn't make it work, if there is some kind of flow we need to follow it would be great to add it to the documentation

Hey @master0v I made this PR that changes the validation_hit implementation to return the response from the debug endpoint, I think that when it gets merged the validation_hit mode should be better
