Adds support for admin-bused pneumatic cannons that fire non /items again (#45957)
Adds support for admin-bused pneumatic cannons that fire non /items again (#45957)

About The Pull Request

Adds an isitem check so load_item doesn't runtime when it adds a non /item into the cannon which admins can trigger using fill_with_type
Why It's Good For The Game

It probably isn't but let's pretend it lets us do something fun other than making a singularity cannon.
Changelog

cl
