CGT: Improve Sleep Talk and boosting sets

[pyuk-bot]

This adds a moveStats object to keep track of information about the moveset so far which should help speed up the move weighing process a little. It also:

• Remembers that Stone Axe and Ceaseless Edge exist
• Makes having an offensive setup move not only lower the weight of moves that don't use it but also increase the weight of moves that do
• Tries to prevent sets from having both Sleep Talk and a status move that doesn't work well with Sleep Talk (which is most of them)
• Lowers the weight of Protect and Endure
• Emphasizes the importance of speed to the power of Gyro Ball and Electro Ball
• Strongly lowers the weight of all status moves on sets with no attacks and only one slot left, especially if they have setup
• Prevents (hopefully) all Poison-immune Pokemon from rolling Toxic Orb, not just Poison Types, and also makes Toxic Orb more likely on Toxic Boost
