Refactor FabricateCandySystem Into Its Generic Equivalent (#566)

# Description
Refactors the nyano shitcode responsible for allowing borgs to dispense
candies into a more generic variant, that allows to define what action
dispenses what entity, and allowing an arbitrary number of such actions
on an entity.
