WARC: from_response incompatible with Requests>=1.0.0

[ersi]

Description/Summary

Seems like warc-0.2.1 is incompatible with requests>=1.0.0. All that needs to be changed is to strip 'full' from 'full_url' and everything will work just fine again.

Environment details:

Python 2.7
warc 0.2.1
Requests 1.0.4

Example code

#!/usr/bin/python
import warc, requests

print warc.WARCRecord.from_response(requests.get("http://archive.org"))

Traceback

>>> warc.WARCRecord.from_response(requests.get("http://archive.org"))
Traceback (most recent call last):
