Weaken divine shock as a spell.

It seems to be the solution to every combat problem before this change, so hopefully this is enough to make it merely powerful, rather than the only tool you'll ever need.
Reducing damage from 4 to 3 and increasing dam_modifier from 3 to 4 causes the spell to do 10 less damage per hit by max level.
Increasing grace from 3 to 4 causes the spell to cost 14 more grace by max level.

+Weaken divine shock without removing the godpower attacktype.
+Hopefully this is enough to make it a solution to every problem.
+Specifically, the changes are:
+grace 3 -> 4 (since the grace increase goes by doubling, this causes a >1 increase in cost at higher levels)
+dam 4 -> 3
+dam_modifier 3 -> 4 (This causes the damage to increase less quickly)

 Give 'mimic' the same client_type as a container so it appears at the same location
 in the player's inventory.
