Support annotating moves in build mode (both with text and !/? symbols)

[GoodChessMind]

Need to enable comments or a hint section to enter while create repertoire. Also, during training need to be able to have the comment/hint section hidden and open it whenever the user needs it

I'm not sure what I think about text hints. I'm hesitant to add too many features that are useful for users that get moves wrong since it seems against the point of the tool (i.e. to not get any moves wrong). The current behavior of drawing a red circle over the correct piece when you get a move wrong seems sufficient.

But having annotations on moves seems very reasonable.

Another user requested this: "Also put some comment on positions (on entering, hint if fail, hint if fail twice)."

Another user requested this: "Hey there! Really liking this tool. Is there a way for us to write notes for each position, or for each repertoire? I think that's the only other thing you could add to send this to the next level! Let me know what you think!"

I really like the tool, but I am also missing the oportunity to add some explanations to the moves in build mode. Something like a textbox below the repertoire tree view, that shows my notes of the currently selected move.

I do not mind if they are not visible in the training mode at all. As you already pointed out, the goal of the training mode is to get them right anyway.
