Artifact and #offer rebalance, part 2: luck from sacrificing

Browse Source 
Luck from sacrificing is now limited by the value of the sacrifice.

This fixes two exploits, both of which rely on getting luck up to
maximum as soon as you have an altar, a luckstone, and a few
rations, via altar-camping until you accumulate enough luck. One of
them is to use the resulting luck to throw off the balance of combat
via using it to make hit chance calculations irrelevant. The other
is to use it to get crowned early in the game; in particular,
getting crowned pre-Sokoban is often viable and, especially for
chaotic characters, solves most of the game's difficulty at that
point (because the intrinisics and weapon are enough to carry a
character to the Castle given even mediocre luck with finding armor).

After this commit, becoming crowned very early in the game is more
difficult (likely requiring unicorns and identified gems), and the
hit chance gain from luck becomes a more gradual gain over the
course of the game rather than all happening immediately upon
finding the altar and luckstone.

In addition to making the game more balanced, this also discourages
grinding by reducing the incentive for altar-camping, so it will
hopefully make it more fun as well.
