- Slate screen reader no longer subscribes to focus change events from Slate application and instead processes focus change accessible events from FGenericAccessibleMessageHandler to
provide the same behavior.
- FScreenReaderBase is now abstract and derived classes must implement OnAccessibleEventRaised to handle accessible events from FGenericAccessibleMessageHandler
- FScreenReaderBase no longer keeps track of all of the registered screen reader users and instead delegates that to the FGenericAccessibleUserRegistry.
- FScreenReaderUser no longer keeps track of all the focus data and instead delegates that to FGenericAccessibleUser
- When the Slate screen reader is constructed, all accessible users will be unregistered. This forces all users to re-register users through the screen reader framework.
-All screen reader user registration of users is forwarded to FGenericAccessibleUserRegistry
