Component Improvements

When EasyUAClient receives an OPC UA extension object that it does not recognize, it now returns it (in reads and subscriptions) as an instance of new UAExtensionObject class. This class allows access to the extension object's body (binary or XML), and its data type encoding ID. Conversely, UAExtensionObject instance can be passed in as a value to be written. This feature establishes basic support for OPC UA complex data types.
All callbacks (including event notifications) originating from the EasyUAClient object are now (by default) sent in a queued manner by a dedicated internal thread, improving resiliency against errors in custom code, and decreasing the possibility of deadlocks. This is similar to what the components for OPC "Classic" were already doing, although the internal implementation is different. This behavior can be turned on or off by the QueueCallbacks property. The idle time before the internal thread executing the queued callbacks is stopped is controlled by the CallbackQueueIdleTimeToSleep property, and the capacity of the callback queue is given by the CallbackQueueCapacity property.

In browsing dialogs and controls that contain the node information pane, the user can now show or hide the pane using the "Node information pane" command on the new Layout drop-down on the toolbar.
Gained more useful screen space in OpcBrowseControl, OpcBrowseDialog, UABrowseControl, UABrowseDialog, in "Browse for Point" dialog, and in Connectivity Explorer (Point Editor) by rearranging control (status bar information moved to the right of the toolbar, and mini-controls over the tree view and list view replaced by context menu items and a Layout drop-down).
