Chrome Extension says "No 'Access-Control-Allow-Origin' header is present on the requested resource."

Not sure how this was working before. But the fix is probably to use django-cors-headers.

Steps to reproduce:

1. Installed the Chrome extension
2. Go to any old github issue

Expected results:
Bid form shown

Actual results:
Extension makes this request:

OPTIONS https://127.0.0.1:8443/bid/?url=https%3A%2F%2Fgithub.com%2Fcodesy%2Fcodesy%2Fissues%2F75

and says

XMLHttpRequest cannot load https://127.0.0.1:8443/bid/?url=https%3A%2F%2Fgithub.com%2Fcodesy%2Fcodesy%2Fissues%2F75. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'chrome-extension://cchpcdoagjopolebepldmfpkcbfoigok' is therefore not allowed access. The response had HTTP status code 401.
