Villager Services

This mod adds a new type of trades to villagers: services. For now, only simple services can be executed, based on the customer (dumb example: send them a chat message). 

More options are currently being thought of, such as:

- Make it so the service can fail at times

- Make it so that the service will have more chances of sucess based on a premium price

- Make the services take time to accomplish

More is possible if using a custom merchant. It could be hired to act as a mercenary for example.

Currently however, I think the best use case is for capabilites, the services could be used to refill mana for instance.
