- new interface. Old FVisualLog class is used only as a devce for visual logger - only to store logs and to communicate with LogVisualizer for now (this class is going to be removed soon).
- added first basic automation tests
- added first simple Blueprint interface
- kept old functionality. ToggleAILogging cheat and EnableAILogging command line works too.
