(QoL) Menuing improvements

[gensakudan]

I'm requesting the following qualify-of-life changes to menuing:

• Pressing button 1 at a Yes/No prompt should always act as though No has been selected.
  • Likewise, at the save slot selection menu, pressing button 1 should go back to the previous menu instead of trying to save in the currently highlighted slot.
• Pressing button 1 when there is a series of menus (e.g. command window -> item menu -> use/equip/drop) should always go back only one menu instead of cancelling all the way back to the command window.
• At any character's status screen, pressing button 1 should return to the previous selection without showing that character's list of battle magic.
