Add an option to find parked domains #39
Description
Many domains are unused and up for sale, but DeadDomainsLinter does not detect them.
Checking of NS record may be used (magpiedns.com,namefind.com,bodis.com and some others)
Also need an ability to enter a list of parking domains. Could be used to test it without default list.
