Migrate old site to github pages

[ed1d1a8d]

Old site was at /athena.mit.edu/anime/

[tesu]

What does this mean, isn't the migration finished?

Ah to clarify, there are some broken links on the anime site like on the historical showings page: https://anime.mit.edu/showings/history
For example scroll down to the 2005 section.

These pages are still in the club locker at /mit/anime/Showing-Announcements on afs.

In the club locker at /mit/anime, there is also /mit/anime/www-oldsite.
