Log bucket liquid placement

[Emojigit]

This PR adds code to log liquid placements done via buckets. Previously, only failed attempts were logged.

This PR is ready for review.

Code looks fine. text in log_action should probably be called something like action? Reordering the parameters to be in the order the message is built (roughly "<name> did <action> at <pos>") could also help make this slightly more readable IMO.

I can definitely see the logging for placing liquids being useful against griefers.

(Why log picking up liquids though?)

Tested briefly, does what it says on the tin, doesn't blow up.

I'm not sure if this technically counts as maintenance, but adding some more logging is by no means problematic.

Reordering the parameters to be in the order the message is built (roughly " did at ") could also help make this slightly more readable IMO.

I kept the order mostly for consistency with the check_protection function above.

Like the engine log digging node, IMO logging this is also needed.
