Attach arbitrary code to entities

[byorgey]

The idea is still kind of fuzzy in my head, and would require a lot more work to hash out a concrete design, but the basic idea is: why not be able to attach code to entities, not just robots?

e.g. perhaps when you use an entity (see #1287), it also triggers any code associated with the entity (which would run with system privileges inside an instant block, perhaps?). This could be really cool for scenario design. e.g. imagine creating a magic wand which upon use causes magical things to happen, like other entities appearing etc. Or imagine you wanted to make a challenge where every time you move it requires using up some kind of fuel. You could accomplish this by creating a new entity with some associated code which moves you and consumes some fuel (in order to move you would have to use thing instead of move).

For a more advanced version, perhaps there could be some way to attach multiple named definitions to an entity, and a way to send it "messages" to trigger the right piece of code.

#1228 seems vaguely related.

I like this idea! It would make commands relatively short (use foo) and create many new scenario options.
