less productivity loss from conversations

From conversation in discord:

* There's a trick I do during conversations, where I start the conversation then as soon as the dialog box pops up I tell my ruler to start something else, and then they're no longer locked in talk mode. It would be nice if that were the default behavior, so that conversations weren't bad for the economy (especially important in tiny kingdoms)
* likely it remains in some form - probably that instead of your ruler following the other person, the other person follows your ruler
* you'll lose the benefit when talking to someone in your kingdom, but really, that shouldn't be a super common, primary use case for the system once it's tuned up properly

* It would be nice if the one following would do tasks that are in range and in their job list -- so like, if I'm talking to Bam Bam and that means they're following me, then if we're near a tree that's set to Cut and they're assigned to logging, they'll start cutting it while we talk
