Additional Option for Dispenser Recipes

**Is your feature request related to a problem? Please describe.**
Items from dispenser recipes are used when they are fired

**Describe the solution you'd like**
I would like to see an option to not use up the items within the dispensers. If these are being used to optimize mob farms and similar, or used in a tutorial area, those items running out are more of a bother than a help - so players will avoid using them.

**Describe alternatives you've considered**
Not using dispensers, or offering the items for cheap in an admin store.

**Additional context**
This specifically came about because I cannot specifically demonstrate this mechanic in a tutorial area.
