Option to hide entities from bonuses GUI

[Thremtopod]

As a followup to this request: it's now possible to hide recipes from the bonuses GUI (which saves my mod from having 20x this problem!), but not entities.

It would be great to have hide_from_bonus_gui for EntityPrototype as well.

Ok, I've added a entity prototype flag for 2.1 to hide them from the bonus GUI.
