Remove invalid DataModels - keep only template.json types

Removed DataModels that are NOT in template.json types array:
- scar, annency-item, boheme, contact, confrontation

Only valid Item types are: equipment, weapon, trait, specialization, maneuver
Only valid Actor types are: pc, npc, annency

Updated:
- modules/models/_module.js
- modules/ecryme-main.js (CONFIG.Item.dataModels)
- system.json (documentTypes)
- modules/models/README.md
