Runtime Error: invalid memory address or nil pointer dereference

@AwolDes thanks for the detailed bug report and the nice words. 2665d14 fixes the bug hopefully.
A minor advice for the above code: The concurrency is not limited what is not adviced (you can DOS the targets or get "Too Many Requests" error). Use LimitRules to control the allowed parallelism for domains or spawn fixed number of goroutines.
Limit example:

scraper.Limit(&colly.LimitRule{DomainGlob: "onslow.io", Parallelism: 2})
scraper.Limit(&colly.LimitRule{DomainGlob: "medium.com", Parallelism: 5})

Thanks for the quick fix @asciimoo! And thank you for pointing out the Limit() function that colly has. I wasn't aware of this, I'll be sure to implement it.
