Better Tool system

[nic-hartley]

Right now tools are... adequate. They can do a lot of interaction by being an Agent, but their capability for I/O with the user is very limited. I'm thinking it needs a bit of a revamp. The trouble is that Apps (by design) can't really act in the same capacity as Agents, so a Tool that wanted to do any event back-and-forth would need to spawn (probably itself) as an agent.

There's probably a solution here around buliding that into the Tool API, but I haven't thought of a concrete answer yet.
