Automatic item and node colorization (#5640)
* Automatic item and node colorization Now nodes with a palette yield colored item stacks, and colored items place colored nodes by default. The client predicts the colorization. * Backwards compatibility * Use nil * Style fixes * Fix code style * Document changes

If the `ItemStack`'s metadata contains the `color` field, it will be

lost on placement, because nodes on the map can only use palettes.

If the `ItemStack`'s metadata contains the `palette_index` field, you

currently must manually convert between it and the node's `param2` with

custom `on_place` and `on_dig` callbacks.

automatically transferred between node and item forms by the engine,

when a player digs or places a colored node.

You can disable this feature by setting the `drop` field of the node

to itself (without metadata).
