Slightly less temporary werewolf code

[Wollywoger]

Quite plain and simple, this is meant to pick up where #561 left off.
this is gonna mostly be a side project for me to work on, as its relevant to a character, and relevant to a later feature/system

plans:

Current

• Give the sprites a second pass
• Add a spell/action that can be given to a player to let them switch to and from their roundstart species and a werewolf
• rebalances and redesigns (bite, silver damage)
• other forms beyond full lycanthrope
• more interesting interaction with silver

Later

• make the body not wholly colored by hair, and ideally have a split between hair and some secondary skin color
• add the ability to have implications outside of werewolf form (eg. weakness to silver)
• add a way to implement it in a modular/configurable by the player way
• "silvered" weapon trait that is used specifically to state something is made of silver, instead of just "holy"

Potential

• Antag? or at the very least, a framework to justify antagonistic behaviors (when greenlit by staff)
• Exclusive/flavored spells
• partial form (PITA because its changing parts, not species, unless i want it to be exclusively humans/human derived)

images when i feel like the sprites are in a good enough state
