Feature/illusioner (#10)

* Initial support for illusioner texture swap

- Copy over illusioner texture from default pack
- Add illusioner texture to evoker entity definition
- Use evoker render controller to conditionally display illusioner texture on q.is_bribed
- Add helmet element to evoker geometry

* Remove animation for duplicates from entity definition

- On examination, it would be too complicated to create the duplicates effect as originally planned, as it would require a follow entity, or changing the visibility of the evoker during attack
- We may revisit this later

* Add documentation for the illusioner

* Fix evoker's weird hat

* Remove JSON compression in favor of one-lining on the CI
