Additional Option for Dispenser Recipes

[ArcticRaven]

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.

I'd question how useful this is as a blanket option.

It feels like a better way of refilling them would be more helpful? (Including admin refills that keep them infinite, I guess)

The recipes utilize resources that are somewhat uncommon (cobwebs in particular) - meaning to make the use of the dispensers worth it, those items need to be just as common as their use.

I guess context is the important part here - this feature works really well for higher efficiency mob farms and such, getting around some needs for water pushers etc. However if the cost of operating the fan/vacuum is more expensive then the cost of running the farm, then this dispenser feature becomes obsolete.

of course - this is assuming 3rd party solutions aren't used to influence the rarity of the resources.
