…ybinds to disable z-level combat cheese (#1159)

* Adds a 1 second delay to moving up and down with the verb/keybinds to disable z-level combat cheese (#81666)

## About The Pull Request

Adds a 1 second delay to moving up and down with the verb/keybinds to
disable z-level combat cheese

## Why It's Good For The Game

Fighting someone using keybinds to move between z-levels over and over
again is damn near impossible. Try it sometimes, it's as bullshit as if
we had bombs that were cross-Z-level.
