Illustrate features using gifs instead of screenshots

[PatrickF1]

Goal

• Use gifs--a video is much better at capturing and explaining a feature than a static image.
• Feature @IlanCosman's Tide prompt manager

For posterity, here is how I'm recording

• remove all Nerd font glyphs from prompt as they don't render with asciinema
• Tide settings: lean, true color, no current time, one line prompt height, compact prompt spacing, few icons
• cd to $HOME (that way, distracting symbols for git states aren't shown in prompt)
• disable autocompletions using private mode or set fish_autosuggestion_enabled 0 (add to config.fish)
• clear terminal screen
• iTerm2 settings: dimensions = 121x33, font size = 16
• record using asciinema, output file outside of git repo so git section of prompt doesn't change
• convert to gif at https://dstein64.github.io/gifcast/
• gifcast settings: font = courier, theme = solarized dark

Resolves #31

Nice 😄 The reason I didn't suggest asciinema was all of the pain you have to go through to get it to work nicely, but you seem to have made quick work of it. The gifs look great!
