Finish and improve fluid implementation

[ExE-Boss]

This PR near-fully implements Fluids.
Fluids are now registered in the following way:

FluidMod(GlobalEvents events, FluidManager fluidManager) {
    events.on(FluidManager.Init.class).bind(evt -> this.registerFluids(evt.manager));
}

void registerFluids(FluidManager fluidManager) {
    fluidManager.register(MOD_ID + ":custom_fluid", CustomFluid::new);
}

To do list:

• Implement 1.7.10 and 1.8 fluid wrappers
