DigiStamp Root certificate

The Root certificates are used to verify that a particular x.509 certificate is issued by DigiStamp. This is commonly a 1-time installation of the DigiStamp Root CA certificate. This action is needed because our Root certificate is not commonly included with, for example, Microsoft or Adobe distributions.
