Artifact and #offer rebalance, part 1: sacrifice gifts

Browse Source 
In 3.6, artifact gifts are often either a) entirely useless or
b) gamebreaking, neither of which is really ideal from a balance
perspective.

This commit aims to make artifact gifts more useful in the early
game by greatly increasing the chance for situational artifacts to
generate positively enchanted.  However, the most powerful
artifacts will now only be gifted if you offer a high-value corpse,
meaning that they are only likely to be accessible later in the
game.  The selection of which artifact to gift has become more
complicated in order to a) increase the chance that it fits the
character and b) reduce cheese strategies (e.g. it is no longer
possible for elves to force the gifting of Stormbringer as the
first sacrifice gift).

artifact gifts are rebalanced (easier to obtain; higher-value sacrifices are
needed for higher-value artifacts; lower-value artifacts are usually
gifted enchanted; unaligned artifacts are possible but rare even on
the first gift; artifacts you can't use well are less likely)

* 1. If the artifact is useful against most enemies, +0.
* 2. If the artifact is useful against only a few enemies, usually +2.
* This gives the artifact use to early-game characters who receive
* it as a gift or find it on the ground.

* default starting weapon (it should be better, but need not be

* (In some cases, like Excalibur, the value is irrelevant.)
* 5. Nonweapon spe may have a special meaning, so gen_spe for
* nonweapons must always be 0.

* Artifact gift_value is chosen so that "endgame-quality" artifacts are
* not gifted in the early game (so that characters don't grind on an
* altar early-game until they have their endgame weapon, then use it to
* carry them through the game). Those artifacts have values ranging from
* around 8 to 10, based on how good the artifact is. Less powerful
* artifacts have values in the 1 to 5 range. Values in between are used
