Latest release (6.0.11) still has old custom http client

[chrislee973]

The latest pip-installable release is still relying on the old custom http client code (in http.py). This was causing errors when passing in a string of the feed content. Installing it from the git repo fixes it but would love to have a new official release!

This is still an issue as of 6.0.12, despite being released 2 full years after this change was made in GitHub.
