Title: HTTP proxy support?

Are HTTP proxies within the scope of the project? I really like the direction the library is heading and use a lot of proxies, so I figured I'd ask w/ a barebones pull request.

I went with `#via` to keep the request chain succinct, but I think `#through` might be more expressive.

Integrating proxies with both Net::HTTP and Curb is reasonably straightforward:
* [Net::HTTP proxy methods](http://www.ruby-doc.org/stdlib-1.9.3/libdoc/net/http/rdoc/Net/HTTP.html#method-i-proxy-3F)
* [Curb proxy methods](http://curb.rubyforge.org/classes/Curl/Easy.html#M000055)
