Remove from field names ending "Key" and "Keys". Consistent singular and plural (for arrays) field names.

Preferably only when there is changes to be made to the table, especially when it comes to popular ones, so we don't annoy people with renames 😄

It's probably smart to establish consistent naming rules across the board. (I noticed you tweaked my key name for Ruthless item costs.) Perhaps we can come up with a good set of guidelines for naming and add it to the README.

This would have to be rolled out in a major version update as it would be a breaking change for anyone using the current schema.
