Updated python-django package fix two vulnerabilities

Updated python-django and python-dgango14 packages fix security vulnerabilities: Stephen Stewart, Michael Nelson, Natalia Bidart and James Westby discovered that Django improperly removed Vary and Cache-Control headers from HTTP responses when replying to a request from an Internet Explorer or Chrome Frame client. An attacker may use this to retrieve private data or poison caches. This update removes workarounds for bugs in Internet Explorer 6 and 7 (CVE-2014-1418). Peter Kuma and Gavin Wahl discovered that Django did not correctly validate some malformed URLs, which are accepted by some browsers. An attacker may use this to cause unexpected redirects (CVE-2014-3730).
