offer an interface to plugin in 3rd party http clients

[dbu]

moved over from jackalope/jackalope#33

being able to plugin Buzz, PEAR::HTTP_Request2 or any other HTTP client for the http communication instead of our own client.

[dbu]

or at least switch to something decent like Buzz instead of the home-grown request that is also the response. need to investigate if the multi-request things can still be done with those libraries.

async multi curl support for Buzz is pending .. for a very long time now :-/
