Added

• Added UI option for The Sol map selection (only shown when the 'sol' mod is installed).

Changed

• Use dynamic layout for map selection buttons so they remain vertically centered regardless of which buttons are visible.
• Update build toolchain.
• Added compatibility with ToTheStars and removed compatibility with ToTheStarsRemake.

Fixed

• Prevent the configuration GUI from reopening briefly when choosing Quit by suppressing automatic GUI open during the shutdown sequence.
