FR: Set-spawn confirmation

[EvModder]

Goal: Prevent accidentally clicking a bed and losing spawn point. Similar in concept to accidentally mining budding amethyst.

Fancy solution: Adding a "confirm" button when clicking a bed

Simple solution: A togglable setting to ignore right-clicks on beds (with a onscreen restriction error, similar to budding amethyst).

This could save fools like myself hours/days of nether roof travel time due to a single misclick
