Barrel/well interaction rework.

[MistakeNot4892]

Description of changes

Really not sure about the implementation of this one. Going to pull it into Pyrelight volatile for testing over the weekend.

• Adds get_standard_interactions() and calls it similarly to alt interactions at the root of attackby() and attack_hand().
• Moves dipping, filling and emptying into interaction handlers provided as needed by the alt interaction proc.
• Barrels and wells also provide these interaction handlers to their standard interaction procs. Basically: you can pick what interaction you want if you have a bucket to fill or empty, or a wrench to unanchor with or put into storage.
• Generalized several structure procs to allow for tool interactions in a similar vein.
• Let barrels be anchored/unanchored.

Why and what will this PR improve

We are at a point where the UX for some structures is getting stupid. Barrels and wells are the most obvious/severe example: if you have a half full bucket, and a half full well, and you click the bucket on the well, the interaction has to be mediated by flag checks and a toggle on the well atom, or workarounds like drag-drop.

This puts support in place for similar interactions in the future, and solves the immediate barrel/well issues.

Changelog

tweak: The way you interact with barrels and well has been significantly reworked; clicking with a bucket or tool should give a list of options to pick from. Please report bugs with this on the tracker.

Something has broken in the fill/pour interactions and now they aren't showing up on barrels. Augh. Issue for tomorrow.

DNM, need to check if this has clobbered hammer deconstruction.
