Use villagers as service NPCs instead

[charliebobgordon]

If we're going to continue having banks and other service NPCs like blacksmiths etc. I think we should use villagers instead, they're more interactive and interesting and can be differentiated from standard players easier as they don't have name tags.

The service villagers would need to be invincible and be able to right clicked just like bankers.

Due to 1.3, this is no longer really feasible, as villagers already have specific purposes.
