villager talk gui concept

This is my idea for minecraft feature, especially for dead adventure mod. Player will be able to talk with villagers and trade with them without pressing alt-fire on them. But also role specific villagers would have special options. For example, player can give damaged items for blacksmith and he will repair it for emeralds. Or priest can restore player's health.

For adventure mod, player can ask some villagers for quests. No idea what, but quests.
