Add whitelisted itemsSuggestion

I've noticed a bug when it comes to planter boxes and GrowableEntities. When people plant Growables into a planter box, it counts those plants against their limits. However, the bug comes in when the plants are harvested, those entities are not credited back to the owner, so they appear to lose those numbers permanently.

Since the plugin just uses short names to identify items, I thought it might be easier to add in a list of items to be "whiteliested" that don't count against your entity limit at all. That way I could just add in the short names of all the GrowableEntities. Thinking this would be easier than checking if the entity is a GrowableEntity, since it's only using prefabs and not the BaseEntity variable.

Will see if I can get this right the weekend.

Awesome! Thanks!

Heya friendlychap, how does it look in this department?

I'd love a feature like this too!
Thanks in advance.
