Notes:
This classs is not available in Xojo 2020r1 or newer.

The plugin is very careful on which events it registers.
All events where you don't have code inside (not even comments), is not registered with the system and you get the default behavior.

All methods in this class will catch exceptions from Cocoa and raise a NSExceptionMBS instead. Using the message, name and reason properties you can see what was the reason for this exception. Please report if you find a method which does not handle exceptions correct.

Please use one delegate class per HTMLViewer (or WebViewMBS) and make sure they live about the same time. Our class keeps a reference on the WebView, so we can remove our delegate when the delegate is destroyed.
