- enchanted arrow explode upon hit the water plane
- non enchanted arrow disappear (or more accurately, they hit nothingness)
- enchanted arrow shot underwater explode immediately
- non enchanted arrow disappear immediately
Also, solve a bug that occured previously and could theoritically still happens where we use the last tested collision position for instead of the last registered hit:
Use the hit position as saved inside Projectile::hit() instead of the last position saved inside the callback.
If a projectile collides with several objects (bottom of the sea and water surface for instance), the last collision tested won't necessarily be the impact position as we have no control over the order in which the tests are performed.
Restore projectile caster from savegame (#5860)

c5426bec In the savegame, projectile caster is identified by its actor id. When
imprecision issue with projectile collision detection.
Simplify the mechanics: manage hits in one spot.
Give magic projectiles a collision shape similar in size to their visible
model.
Rename the 2 convex result callback to clearly state their purpose.
When an NPC fire a projectile, it should affect only its targeted actor.
To this end, after a hit is detected the target is checked against the
list of AI targets and reactivated if necessary.
Problem occurs when the hit occurs as a result of a friendly actor going
into the projectile (detected in ClosestNotMeConvexResultCallback):
while the projectile is inside the friend's collision box, it is
deactivated, just to be immediately reactivated. Effectively, the
projectile does nothing until the actor moves out.
Add a check inside the ClosestNotMeConvexResultCallback before declaring
a hit.
Since the necessary data is not safely accessible from the async thread,
maintain a copy inside the Projectile class.
1. Move weapon types behaviour from switches to the table (should allow
us to de-hardcode weapon types later)
2. Gereralize bones injection to actors skeletons (instead of using the
hardcoded xbase_anim_sh.nif)
