Summary

This PR proposes using https instead of http for the stylesheet https://www.google.com/cse/style/look/default.css. Currently, Chrome 70.0.3538.102 on macOS blocks that stylesheet from being loaded via http, with the error:

Mixed Content: The page at 'https://nipype.readthedocs.io/en/latest/index.html' was loaded over HTTPS, but requested an insecure stylesheet 'http://www.google.com/cse/style/look/default.css'. This request has been blocked; the content must be served over HTTPS.
