5.1.1511

adjusts Nightar balance somewhat, and cleans up their light effect code.

They now suffer energy and health penalties in sunlight (up to 20%), and their damage bonus is more seriously reduced (was 25%, dropping them to 75% in sunlight. It now drops them to 62% instead) as well.

Both Penalty and Bonus now use effectiveMultiplier, which will make them more viable/dangerous at any given tier.
