after_http_request hook

The after_http_request hook gets called with each request and response just after a request has completed. It can be used for many things:

* globally logging requests and responses
* ejecting the current cassette (i.e. if you inserted it in a
  `before_http_request` hook)

You can also pass one or more "filters" to after_http_request, to make the hook only be called for some requests. Any object that responds to #to_proc can be a filter. Here are some simple examples:

* `:real?` -- only real requests
* `:stubbed?` -- only stubbed requests
* `:ignored?` -- only ignored requests
* `:recordable?` -- only requests that are being recorded
* `lambda { |req| URI(req.uri).host == 'amazon.com' }` -- only requests to amazon.com.

log all requests and responses using after_http_request hook

Given a file named "after_http_request.rb" with:

ruby

include_http_adapter_for("<http_lib>")

$server = start_sinatra_app do
  get('/foo') { "Hello World (foo)" }
  get('/bar') { "Hello World (bar)" }
end

require 'vcr'

VCR.configure do |c|
  <configuration>
  c.cassette_library_dir = 'cassettes'
  c.ignore_localhost = true
  c.after_http_request(:ignored?, lambda { |req| req.uri =~ /foo/ }) do |request, response|
    uri = request.uri.sub(/:\d+/, ":7777")
    puts "Response for #{request.method} #{uri}: #{response.body}"
  end
end

make_http_request(:get, "http://localhost:#{$server.port}/foo")
make_http_request(:get, "http://localhost:#{$server.port}/bar")

When I run ruby after_http_request.rb

Then the output should contain "Response for get http://localhost:7777/foo: Hello World (foo)"

But the output should not contain "bar".
