Multiple headers with same name

[Dreamescaper]

Do I understand correct that currently it's not possible to set multiple headers with same name to ResponseMessage?
In particular, I'm interested in providing multiple Set-Cookie headers.
Is it possible to add such functionality? I could submit PR with changing Headers property from 'IDictionary<string, string>' to something like 'IDictionary<string, string[]>', but not sure how great is that, considering that it is public member.

First change will be:

IResponseBuilder WithHeader([NotNull] string name, params string[] values);

Also your idea is possible:

IResponseBuilder WithHeaders([NotNull] IDictionary<string,string[]> headers);

However, also the json parsing should be updated. I will take a look.

Added PR with simple implementation for that.

Thanks.

I added the JSON part to your code. Please review.

And if it's ok, I can create a NuGet.

Great, thanks!
