Feature Request: Support .txt Files

[mutewinter]

And perhaps other common document types. I believe that Readability supported these with a hard-coded exception based on file extension or mime type.

curl -H "x-api-key: API_KEY_HERE" "https://mercury.postlight.com/parser?url=https://wordpress.org/plugins/about/readme.txt"

Returns null

This is verified by the result that is being returned via the above curl command
