Island Postcards: collectible loot #316

Add new Entitydefaults for each zone of some new category
Add new category under syndicate items
Set flags for stackable, and probably nothing else
Make new relic type for each zone, add each loot to each relic type, and add each relictype to the relicspawninfo for each zone it is paired with.

Result, unique relic dropping unique loot for each zone. A postcard to remember their trip :)
