Add 'Confirm Move' toggle setting for mobile users #198
Description
Mobile users report many accidental moves/clicks, which can be prevented by a confirmation before every move made on mobile devices.
Essentially, there should be a move confirmation toggle setting within the /settings page. When this is on, any move made in the /play/maia, /play/hb, and /puzzles page should have a button that asks the user to confirm that they want to make that move before actually making that move. When a player makes the move, it should show on the gameboard but no functionality should be done. Finally, when the player confirms the move, it should actually continue with the game or finish the puzzle and such.
