Unlit Campfire

Added

• new behaviour that a (soul) campfire decreases the light level for the last 30 seconds (configurable, can be deactivated) (all loaders) (thanks to Acenthus for the idea) #38
• new configuration options "campfireMaxLitTimeExtension" and "soulCampfireMaxLitTimeExtension" to extend the burn time beyond the normal burn time when adding burnables (all loaders) (thanks to Fer0x453 for the idea) #42

Changed

• number config options are now text fields instead of sliders (Fabric)
