HighByte Intelligence Hub Version 1.1

Improved user interface / experience configuring the Intelligence Hub:
- Shallow cloning of connections, models, instances and flows
- List pagination for large datasets (a connection's input and output lists
- Search filtering
Flows now support 4 triggers: Always (1.0.0 behavior), OnChange, OnTrue and WhileTrue.
Flows now support 2 publish modes: All (1.0.0 behavior) and OnlyChanges.
Added description field for connections, models, instances and flows.
Added support for nested models / instances.
Added OPC UA support for data values of type DateTime. An appropriate error message is now logged when encountering an OPC UA data value type that is not currently supported.

Improved user interface error handling / messaging in the event a connection to the runtime service fails.
Fixed task scheduling performance issues related to reading inputs, constructing a model, running expressions and publishing the results as compared to the configured interval.
Fixed issue where a modeled instance's published value did not maintain the attribute order set by the user (attributes were incorrectly sorted alphabetically).
Fixed OPC UA connection validation issue when an endpoint uri contained uppercase characters in its hostname.
Fixed user interface performance / scalability issues around large datasets (OPC UA browse results and a connection's input and output lists).
Updated Paho Client MQTT library to 1.2.4. This update resolved an issue related to re-establishing a connection with a broker when one or more persistence (QoS) files were left over from a previous run.
