Imgur direct link to album page redirect blocker per esha

Blocks Imgur from redirecting direct links such as "https://i.imgur.com/examplelink.png" to "https://imgur.com/examplelink".

Normally doing a request with "text/html,application/xhtml+xml" in Accept header lets Imgur know that we are using a browser and then reply with "Location: https://imgur.com/examplelink" which will redirect it to the album page instead.

This addon will replace the Accept header with "*/*" to force Imgur to deliver any media as-is as it can't rely on the request to be a browser at this point.
