Removed rule for Tradera.se

Tradera has recently rebuilt their site. If you try to access the HTTPS-server, they will just redirect you to the HTTP version of the site. There is currently no way to force HTTPS for this site. Additionally, this rule currently makes the site non-functional (see #49, problems with Access-Control-Allow-Origin).

I have therefore removed the rule, since it is non-functional and cannot be fixed.
