py-m2crypto: updated to 0.30.0

0.30.0:
- Various small typos (Windows builds, Fix SSL.Connection.__del__)
- The project is now Linux-distribution agnostic
- Replace all old-style classes with the new ones (it shouldn't cause
  any problems, but feel free to file an issue, if it does)
- Do not by-pass a potential transfer decoding in m2urllib2
- Update M2Crypto.six with 1.11.0 and replace our local workarounds with
  new functions.
- SSLv3 just removed.
- Don't support Python 2.6 on Windows anymore. Windows users don't have
  python as a system package, so they are usually more likely to upgrade
  anyway.
