Describe the solution you'd like
/pmmo genData to create a folders/files to tag entities for it, such that they only have to have their IDs entered.

Why is this feature needed
Right now it requires more than a little research and testing for users to understand how to create such.

Describe alternatives you've considered
A specific command /pmmo genData entities, but I think it would be best to just make them and leave them ready to populate.

Additional context
Here is a butternut pumpkin.
