Patched Carrot per ajxu2

This is a patched version of the Carrot extension.

Carrot is a browser extension that enhances Codeforces ranklists by showing the performance rating and predicted rating change for each user. However, it no longer works during contests, since the domain codeforces.com blocks automated requests while a contest is running.

Patched Carrot fixes this issue by sending requests to a mirror of codeforces.com instead. This allows the extension to function normally during a contest.
