Fix newline_wait option

Need to use the curses version
Add debug Log

This can be enabled in the config and written to with `Log.log`.
Add configurable Spawn behavior

`InstantSpawn` is the same as we've had and spits out as many agents as are
ready.
Add TickSpawn

It doesn't spawn ticks, it just spawns some number of available agents per some
period of ticks.
Show agents-in-play on the scoreboard

Since agents can be queued now, this becomes an interesting number.
