Fixed typo in 'AXIETY_PROPENSITY' in centaur raws. Lowered some creatures frequencies and cluster sizes. Made centaurs a bit smaller again.

Made some creatures less annoying to deal with (namely Giant Wargs and Basilisk). Gave all relevant creatures portraits. Completely redid centaur graphics to make them smaller, as well as giving them full layered graphics support and portraits. Rebalanced Centaurs heavily, making them much smaller and giving them more skills and learn rates.

Last update added the syndrome token to make fortress and adventure mode syndrome timers match, but didn't actually update said syndrome timers to reflect this, causing syndromes to last a very long time. They have all been changed to have a more reasonable timer. Also changed the phoenix and fenrir's body temperatures to not kill whatever is wearing leather made of their materials.

Fixed small typo in giant fae dragon's breath material.

• Added 6 new creatures. Basilisk, Mandrake, Owlbear, Tressym, Stymphalian Bird, and Undead Dragon (megabeast)
  
• Added 1 plant: the mandrake root. Upon death mandrake will drop a seed that can be planted underground and makes an extremely potent booze. It can cause extreme pleasure in dwarves and even heal some illnesses, but as it's also extremely toxic it has a long list of harmful effect it can also rarely cause.
  Note that because it's a subterranean plant it'll be available on embark, unless somehow dwarves didn't breach the caverns in world gen.
  
• Added 6 giant variants. Griffon, Bicorn, Fae Dragon, Stymphalian Bird, Chimera, and Warg (uses old warg sprite)
  Note you cannot actually limit a creature to use both [GOOD]/[EVIL] AND [SAVAGE] so in the case of the bicorn, fae dragon, and chimera, they can spawn in any spirit of savage biome from the base creature's original biome list.

• General minor sprite improvements
  
• Warg now has a new, 1 tile big sprite to better fit it's size.
  
• Cleaned up some unused sprites from the sprite sheet.
  
• Added two new colors wyvers can be in the new freed tiles (black and yellow).
  
• Wyverns didn't actually have a [CHILD] tag before, now they do.
  
• Wyverns fireball interaction was changed from [ATTACK] to [DEFEND] to help them not burn things down as much. They also now have the [MEANDERER] tag.
  
• The four types of living armor are now separate creatures instead of caste of the same creature. They still function the same, but now they can spawn in different layers of the caverns. Iron now spawns in layers 1-2 with a frequency of 5, bronze spawns layers 1-3 with a of 4, steel spawns layers 2-3 with a frequency of 3, and adamantine spawns in the magma sea and HFS with a frequency of 2.
  
• Added a lot of body definitions to make creatures covered in the 'correct' materials on parts of their bodies.
  
• Balance changes to megabeast. Cockatrice is now stronger, and now spawns at 3/3/3 difficulty. White dragon, wurm, and leviathan's breaths made into multi emissions, making them deadlier.
  

Fixed leviathan not having eyes due to a typo, made leviathan's body temperature/lightning slightly cooler to make fighting/pathing around them easier. Gave female sphinx spots descriptors. Made Centaurs and sphinx bigger to match their sprites more.
