Fixes for the german translation.
Change vendor items of kenrik and the captured trader

Kenrik doesn't offer any epic gear now, but instead greatbow/staff/sword
and the very best normal shield.

The captured trader is an insiders hint: you get all the epic gear here.
Including rings, figurines and some mage equipment.
Add level 3 gear to specific bowyer, smith and alchemist
