setCookie resets other cookies

[jakajancar]

setCookie in std/http/cookie.ts will reset other cookies being set (replace the entire Set-Cookie header). I did not expect this.

Perhaps the easiest fix is to change from:

setCookie(res: Response, cookie: Cookie)

to

setCookies(res: Response, cookies: Cookie[])

Alternatively, perhaps res.headers.append() can be used in setCookie.

As it stands now, there is no way to set/modify two cookies in a single response with these utilities (e.g. session id and nonce for OAuth).
