[Security-sig] New report of Python vulnerabilities

Hi, I made major enhancements in my tool to generate reports on Python vulnerabilities. * A timeline is now automatically generated using the different dates: initial report date, disclosure date, commits, Python releases, etc. * CVE details are now downloaded automatically, so it's not more filled manually in the YAML file. * Each vulnerability has now its own page Good example showing everything altogether, the Sweet32 attack: http://python-security.readthedocs.io/vuln/cve-2016-2183_sweet32_attack_des_... The next step is to make sure that all maintained branches got a fix! I should enhance the tool to compute the list of vulnerable Python versions. Victor
