Disable scripts.mit.edu/~username/

[adehnert]

For various reasons, we should stop serving scripts.mit.edu/~username as roughly the same as username.scripts.mit.edu.

(We've known this for a while. Mostly I'm hoping to document what the blockers are here.)

Anders claims that the only thing left is checking if any Wordpresses think they're at scripts.mit.edu/~username, and if so fixing them.

Despite similarity in the names, #93 is unrelated.

That’s #17.
