Tasks should emit actions

When a task is performed, the server should make the entity involved in the action emit actions, so that the clients can show animations or play sounds.
Some examples:
* When logging, "cut" or "chop" actions should be emitted.
* When reaping, "reap" actions should be emitted.
* When cultivating, a "sow" action should be emitted.
And so on.

The other option would be for the clients to see the task and emit events for it, but I don't think that's a viable direction.
