Merge pull request #205 from minrk/bundle

bundle libzmq as an Extension if it isn't found

The code to do this is largely from pyzmq-static, but with some important differences:

* libzmq as an extension is *optional*
* libzmq/uuid sources are downloaded as-needed
* platform.hpp is attempted by ./configure before falling back on
  shipped versions (also from pyzmq-static)
  
This should make pyzmq pip-installable without libzmq present, and remove the need for the pyzmq-static project to exist separately from pyzmq itself.

closes #128
