Rack dependency

[oriolgual]

Right now Rack is declared as a development dependency but Pusher::WebHook uses Rack::Request here.

There are two solutions: add Rack as a dependency or (better IMO) change the if to something that just checks if the given object quacks like a Rack::Request.

What do you think?

Yes this is a good point. We use rather a lot of methods to check for all those quacks, how about something like this?

if defined?(Rack::Request) && request.kind_of?(Rack::Request)

Works for me :)
