[b42] Minor item generation bugs

[drayath]

Below ~dungeon level 1000 the item generator fails to create items of some types

game.state:generateRandart{base="dwarven lantern", lev=1020, 4}
game.state:generateRandart{base="voratun torque", lev=1020, 4}
game.state:generateRandart{base="dragonbone totem", lev=1020, 4}
game.state:generateRandart{base="dragonbone wand", lev=1020, 4}

For torques, totems and wands the getName() of an unidentified item includes details on the item.

E.g. shield will always show as "Vortrum shield" where as a wand might show as a "dragonbone wand of conjuration" or "dragonbone wand of healing". To match other items would expect it to just show as "dragonbone wand"
