[QuestGrinding/Grinding] Add more data to profiles and expose them

[Bia10]

Well i think it would be good idea to have data like Vendors/Trainer/Mailboxes localized in profiles rather then somewhere global, i am also open to discussion wherever FreeBagSlots or SellByItemQuality shouldn't also be included as sometimes i would want less free space sometimes more free space depending on profile not a global settings.

• Add Vendors to profiles
• Add Trainers to profiles, Vector3 Position, string Name, TrainerType Type
• Add Mailboxes to profiles

initial implementation done in #94
