Added ClouDNS and SaltStack

* *SaltStack* i a great tool for system administration and remote management. It's getting more and more popular. For me it's much more comfortable than Puppet for instance.
* *ClouDNS* is a DNS hosting service in a cloud. There is even free plan available. But paid plans, which give you unlimited domains are also riddiculously cheap.
