response: combine header fields with the same field name

[algesten]

@jsha as an alternative, we could opt for retaining the current semantics of header(), that is returning first value, also for concatenated headers, and add a second:

    pub fn headers<'a>(&self, name: &'a str) -> &[&str] {
       ...
    }

This would return all values, concatenated or not. The advantage of that would be:

• Retain (clarify?) semantics for current header.
• Offload splitting/handling multiple values. This is otherwise pushed over to user of ureq to handle.

Actually, I hadn't noticed Response.all, which has the semantics of returning all values for a given header field name. I think that fills the need well enough for now.

Oh. I forgot about that one :D
