Fluid Container API — Luanti Mod by IcyDiamond

This is a fluid container and transfer API for Luanti. It augments the default bucket mod and adds these features: * Nodes can now have "internal buffers" of fluid. * Buckets can be registered with a color instead of an image. * Buckets have callbacks that can insert and take fluid from certain nodes with internal buffers. * Fluid storage tanks! * Fluid transfer nodes! **Note 1:** Default storage tanks are registered for all fluids that have a bucket. **Note 2:** "Compatible games" list only shows games, where the bucket_compat compatibility library is officially supported. There shouldn't be reason for this mod not to work anywhere else, except for potentially the bucket-directly-into-node placement. API documentation is available in the README.
