Add prompt selector
It's a bit weird to *have* to fire up a browser to get fish_config to choose a prompt. So this adds a `prompt` subcommand to `fish_config`: - `fish_config prompt list` shows all the available prompt names - `fish_config prompt show` demos the available sample prompts - `fish_config prompt choose` sources a prompt - `fish_config prompt save` makes the choice permanent A bare `fish_config` or `fish_config browse` opens the web UI. Part of #3625. TODO: This shows the right prompt on a new line. Showing it in-line is awkward to do because we'd have to move it to the right.
