permit insecure connections with urllib2.urlopen in python 2.7.x >= 2.7.9
# Because migrating to python 2.7.9 requires me to update my code (or ask my clients to add cafiles to their trust store
# [which some people don't know how to do]), I found a way to explicitly allow insecure connections (ie. without hostname
# verification) using urllib2.urlopen()
#
# This gist basically involves creating an ssl.SSLContext() with some options which disable hostname verification
# This allows you to, for instance, add a parameter to a function which disables hostname verification.
