This allows for marking certain bindings as part of a preset, which allows us to - only erase those when switching presets - go back to the preset binding when erasing a user binding - only show user customization if requested - make bare bind statements in config.fish work (!!!11elf!!!) Fixes #5191. Fixes #3699.
