ACF5: Delete circles vgears after wave3 appeared

Keep track of accuracy record in target practice challenges

Remove "loser" messages in challenges The point of challenges is not to "win", but to reach a highscore, so we need not to rub failure into the player's face.

Rename the special "none" key in frontend

branch merge

ai improvements are release branch safe
