Update 1.31

• Updated Corner Messages to be more readable
• Rolling for save items in non-consistent mode no longer biases enemies killed later, making the distribution of items far more fair and balanced.
• Added a setting to grant additional save items based on the number of the enemies in the map.
• Updated default settings to be more dynamic and feel more natural.
• Fixed off-by-one errors that were sometimes preventing the final save item from dropping if it was rolled by the last enemy in a map.
