Remove the automappings

[patrickmj]

Consensus from testers is that the textbox of automappings from @Daniel-KM 's branch is a bit much for our users, so need to take it out and adjust other modules' configs accordingly.

This is a feature I need, so because the feature is now a controller plugin, it's possible to override it inside another module (some details may be fixed). So there is no issue to remove this feature for me.
