Update SSL configuration for https://classics.mit.edu

[robertknight]

The site https://classics.mit.edu/ has an old SSL configuration which causes difficulties when attempting to fetch pages with certain tools.

For example, this Python snippet:

import requests
requests.get("https://classics.mit.edu/Aristophanes/eccles.html")

Results in the error:

requests.exceptions.SSLError: HTTPSConnectionPool(host='classics.mit.edu', port=443): Max retries exceeded with url: /Aristophanes/eccles.html (Caused by SSLError(SSLError(1, '[SSL: DH_KEY_TOO_SMALL] dh key too small (_ssl.c:1010)')))

We'll look for a workaround, but I wanted to report this in case the issue can be addressed on the server side.
