Introduce 'on change' actions that are triggered as soon as an UCI option is changed by the GUI. This allows to set hash size before to start the game, helpful especially on very fast TC and big TT size. As a side effect remove the 'button' type option, that now is managed as a 'check' type. No functional change. Signed-off-by: Marco Costalba <mcostalba@gmail.com>
