New resolvers

The resolver in Zurich, CH has been removed as Kuroit has closed that location. They're sponsoring our new resolver in London, UK instead.

Thanks to generous sponsors Skhron, IncogNET and Crunchbits, I've been able to add four more resolvers to the project: Warsawa, PL / Naaldwijk, NL and two US locations (Liberty Lake, WA / Spokane, WA).

Another resolver in Phoenix, AZ has been added.
