Support for multiple cookies

[leandromsales]

Hi folks...

In a simple test I was running, the webserver sent the following response header:

Date: Thu, 26 Nov 2015 23:07:42 GMT
Server: Apache/2.4.16 (Unix)
Set-Cookie: CookieTesteName1=CookieTesteValue1; expires=Fri, 27-Nov-2015 00:07:42 GMT; Max-Age=3600; path=/folder; domain=.domain.com; secure
Set-Cookie: CookieTesteName2=CookieTesteValue2; expires=Fri, 27-Nov-2015 00:07:42 GMT; Max-Age=3600; path=/folder; domain=.domain.com; secure
CustomHeaderName: CustomHeaderValue
Content-Length: 2397
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: text/html

Please, note that there is two "Set-Cookie", but response.headers["Set-Cookie"] using cordova-plugin-fetch only returns a string containing the last "Set-Cookie" value. Is this the expected result?

See #138 and #163 for a discussion of forbidden headers and cookies.

In the general case, with the exception of forbidden headers, the expected behavior is to append all values for each header to the headers list. For example, if the response includes these headers:

Server: Apache/2.4.16 (Unix)
Server: nginx

then accessing the Server header returns both values:

values = response.headers.getAll('Server')
// => ['Apache/2.4.16 (Unix)', 'nginx']
