First OPC-UA implementation.
Major features:

• OPC-UA with Eclipse Milo.
• Support to Anonymous, UserPass and X509
• Support to both tag refresh rate and publication window
• Improved testing and documentation.

Some breaking changes:

• OpcOperations become an interface. Implementations are now OpcUaTemplate and OpcDaTemplate
• Opc Auto connect now removes unnecessary cast thanks to dynamic proxies.
