Added initial logging support.

The idea is that you can log your requests using either the include syntax and the direct HTTParty class.

Using include:

class GoogleFetcher
  include HTTParty
  logger Rails.logger
end

Using HTTParty:

HTTParty.get "http://google.com", :logger => Rails.logger

I have included two log styles, one that resembles apache's access log and another that resembles curl, which can be used by passing :log_format => :curl.

You can also control which method is called on logger by passing :log_level => :debug for example.

Please let me know if the code does not adhere to the project's standards or if I need to change anything.

Opinions and criticism are welcome.

Travis CI is showing a test failure. Can you fix that up?

Won't this make it always use the same time?

Getting really close. Thanks for all the work!

The memoization was there because it was hard to test using Time.new. But since I am testing using regexp, I don't need it anymore.

Also, I created the raw_body method as requested.

Merged. Thanks.
