Because it should never show up in the normal global/extruder settings tab, people might forget about this setting. It's one of the reasons per-object settings is awesome ^^.
The function it calls no longer exists. The protobuf message it listens to was renamed and the renamed message is properly listened to in the line above.

This was required since Cura 2.1 produced files with the same filename (bar extension). This then resulted in two containers with the same ID. If you had bad luck, an instance container was chosen as global container (depending on which was first in the unordered dictionary). This gives the current settings the postfix _current_settings, fixing that issue.

Why there is a difference between 'general' and 'metadata', only His Noodleness knows. Also put in a default for the type. It should apparently be 'quality' unless it is a user profile.

I'm not quite pleased with the variant translation being inside this function, so I'll move it to VersionUpgrade21to22 soon I think.

A translation dictionary makes it much easier to edit the translations. Also this now just translates one printer, instead of a list.

This solution is a bit neater in code. It makes the function perform a single purpose, since it no longer translates a list of setting names but just one. Also it now neatly puts the translations in a separate, easy-to-modify dict. Only disadvantage is when simple key look-up is not sufficient, such as when renaming lots of settings at once, where substring matching would make the code a bit shorter. But we shouldn't do such a rename anyway.

It is not entirely accurate in the translated version, since the new current_settings is not machine-dependent any more. However, without information on the original file name, this is as good as it gets, since that instance profile there only mentions the machine it is dependent on in the file name.
