Sequence Updated

Patch notes:

- Save Slots have been added to the main menu.
- Fixed a bug where quitting to the main menu directly following a lost battle, and then subsequently attempting to access the Bonus screen would crash the game.
- Fixed a bug where equipping the final item in the current pane to a blank equipment slot would allow the player to move his or her item cursor freely and crash the game.
- Fixed a bug where directly closing the game window directly after synthing an item could lead to out-of-bounds experience point values.
