+- Jitter sleep times in together ai wrapper. This may improve speed.
+- Change AllSimilarMemories component so that it no longer weights retrieval by recency or importance. This will make it function more like its name suggests it should. Note that many agents use this component so their behavior may change as a result of this change.

+- Add seed parameter to all simulations, propagating it into sample_parameters
