Wrong item data

The information about the level requirements for most of the jewelries (old and new ones) are wrong:

*the low level rings, amulets and belts have no requirement at all (not 2)

*the single attribute amulets have 5, not 7
*gold amulet is 8, not 15
*onyx amulet is 20, not 25
*hybrid attribute amulets are 16, not 20

*leather and heavy belt are 8, not 10
*cloth and studded belt are 16, not 20

*gold ring is 8, not 10
*resist rings are 11, not 10
*diamond ring can at least be 20 (have only a rare one yet), not 25

(information about moonstone & amethyst rings will be added on availability.)

completion:

moonstone and diamond rings are base level 20, amethyst ring is base level 30 (not 38)

bump with funny information ^^

the only jewelry item with the correct level requirement is the prismatic ring.
