Middleware contract has been deprecated in 5.1

[thijsvdanker]

See http://laravel.com/docs/master/upgrade#upgrade-5.1.0

The middleware contract is deprecated in 5.1 and will be removed in 5.2 (due december 2015).

@thijsvdanker Thanks, I miss the latest changes. This guy keeps changing things that makes BC problems :@

I am not sure if this can bring problems with 5.0, I think it force you to implement the interface. Doesn't it?

I think I will create a decorator for 5.0 that wraps this class without the contract, how does it sound?

There should be no issue removing the interface. The interface only defines the necessary methods a class should have. Also if your concern is related to IoC binding, I can tell you that an interface is not required for the class to be bound into it.

Also supporting 5.1 is a bit more valuable, seeing it is the Long Term Support (LTS) version. But it's up to you to find the correct solution in your package. Good luck and nice work!

Thanks @luceos, the thing is that I wasn't sure if the middleware pipeline explicitly check for middleware subtypes, if this is not the case it shouldn't be a problem.

I will check the Laravel docs and implementation in 5.0 and then merge this PR.

Thanks guys
