Adds two new quality levels, the level 10 Unreal and the whopping level 24 Mythical. Higher qualities are harder to reach, but the ceiling becomes very high.

• Legendary quality becomes available after conquering the three inner planets.
• Unreal and Mythical become available after Aquilo, with configurable progression.

Epic and higher qualities have reduced probability (all of these probabilities configurable):

• Epic is down from 10% → 8%.
• Legendary is down from 10% → 6%.
• Unreal has 4% probability.
• Mythical only has 1.75% probability.
