Removes Code Climate reporting, sadly the package is riddled with security issues

Uh, I don't think that's a good reason to remove the badge + reporting.
I think we should try to fix those issues instead.

@Thor77 the code climate reporter we were using has critical security issues and has been deprecated. It's nice to have, and we can look into integrating their new reporter.

But considering the following warnings, I thought it best to remove it as soon as possible.

[!] 8 vulnerabilities found [180 packages audited]
    Severity: 1 Low | 5 Moderate | 1 High | 1 Critical
    Run `npm audit` for more detail

Oh, you're absolutely right. I understood your message as

Removes Code Climate reporting, sadly the package [wunderline] is riddled with security issues

and therefore it seemed like a bad decision to me.
But yeah, integrating the new reporter is still a good idea.
