Particles and some minor adjustments

[IchHabeHunger54]

This PR adds the particles and visual effects Ars Magica 2 was famous for into the mod. Specifically, it:

• Adds various new particle types with textures from the old mod, some of which were reworked into the JAPPA style
• Adds the AMParticle class that can take any other particle's appearance
• Adds a particle controller system that allows for complex particle movements to be defined
• Adds a particle spawning system that runs on the client upon receiving a packet from the server. The server does not spawn the particles itself, making the system suited for multiplayer
• Adds particle spawners for all components that had particle spawning in the old mod, staying as close to the old design as reasonably possible
• Replaces the old particles on some of the entities (projectile, wall, wave, zone, blizzard, firestorm, falling star, mana vortex) with proper new particles
• Integrates with the Color modifier (see #355 )

It also does some other minor adjustments:

• Changes the beam shape's color depending on the spell's primary affinity
• Changes some implementation details on some of the spell parts
• Fixes SkillHelper to not crash when leaving the end (we had like 5 issues like this now, I'm growing tired)
• Replaces the LivingEntity::canBreatheUnderwater call in AMSpellParts with a call to the new fluid system
• Adds missing loot tables for the three inlay blocks
• Adds new API methods for getting the spell item stack from an entity or from an interaction hand
• Removes AMUtil.nextDouble and replaces its uages with direct RandomSource#nextDouble calls
• Removes various overrides of Entity#isPushable, courtesy of IntelliJ's new "method is identical to supermethod" inspection
• Removes the ItemSupplier implementation on various entities (it was never actually needed for anything except Projectile)

This is a draft PR for now, so that people can review it. It will be marked as ready once all particle effects have actually been implemented.
