Added

• Define command completions for fzf_configure_bindings (#177)
• Skip config if not in interactive mode, which makes non-interactive fish shells (such as those created by tide or fzf previews) faster (#180 - @kidonng )

Fixed

• Fix default key sequence docs in fzf_configure_bindings (#175 - @jonashaag )
• Make sure --variables flag has trailing 's' in docs (7ff05ca)
