Make the use of cans more like the digging and placement of ordinary nodes, and specifically make it much closer to the use of buckets. The main change is that left-click with a can is now only used to take liquid; placing liquid is now done with a right-click. This makes the use of cans a lot less error-prone, compared to the old scheme of determining the operation based on the type of node pointed to. Other changes are that liquid placement is now permitted to replace any buildable_to node, and the cans obey node protection.
