Fixes for gamebreaking metabolism rates

- A single chili doesn't kill anymore
- Chloral hydrate no longer kills in amounts of 2 units
Doubled metabolism rates.

This puts metabolism back between where it was originally, and where the metabolism rebalance put it. Thus it shouldn't break anything, but it'll make most chemicals a bit more usable.
Tajaran ear stuff, originally by chinsky
