AI-driven comment buttons moved to the Engine Window

[whelanh]

The "Auto Comment" button that was in the PGN Window and the "Auto Comment" that was in the Analysis Engine Window have both been moved to the Engine Window. This was to allow better AI prompts that can now take take advantage of always present PV lines from the engine and the comprehensive view of the game provided by the engine score chart and player accuracy numbers that are automatically created in the Engine Window.

A comment on a single move is created with the "Auto Comment" button. To use properly, set your engine to multi-PV mode (3 lines), then go to the move right BEFORE the move you are interested in and let the engine run for a short time, then move forward to the move you want the comment for. Stop the engine and then press the "Auto Comment" button.

Comments for every annotated move (which can be done using the Annotate Button in the Analysis Engine Window) and a final "Game Summary" comment can be created at once by pressing the "Game Comment" button.

The location of both buttons is in the lower right of the Engine Window. User suggestions for the prompts that are used continue to be welcome.
