The [clarin-sp-aaggregator](https://github.com/ufal/clarin-sp-aaggregator)
hasn't been working for some time.  Digging into the details showed that
we broke the functionality with d6a64be5 while fixing #62.

Here, we fix the problem: connect to 127.0.0.1 via http on port 443.

Fixes #70

`easy_install` does not support https, which has been made mandatory for
pip packages. `pip` supports it natively.

git cherry-pick --edit 849d02d1
