Add top CLI tools from "Who needs a GUI?" article

[waldyrious]

@BryanLunduke's "Who needs a GUI? How to live in a Linux terminal." presents a list of the best CLI tools after attempting to go GUI-less for 30 days. These are probably good candidates for us to cover.

• mutt (common / linux)
• notmuch (common / linux)
• alpine (common / linux)
• w3m (common)
• nano (common)
• wordgrinder (common / linux)
• cmus (common / linux)
• finch (common / linux)
  • Guide to Using Finch - Terminal-Based Chat Client
  • Finch - Howto use Pidgin via Terminal Console
• hangups (common / linux)
• rainbowstream (common / linux)
• rtv (common / linux)
• htop (linux)
• mc (common / linux)
• tmux (common)
• screen (common)
• tpp (common / linux)

Most of these are interactive tools, which will present a challenge for documenting them in the tldr format, but if we can do vim and nano, we can do these as well :)

Hi, I've started to document some of these.
Should be done very soon.

Update: mc and wordgrinder are now done, and there's a PR for mutt on the way :D

@waldyrious mutt and tpp seem to exist. Will this be updated?

Thanks, updated.

Only 3 to go (notmuch, finch and rainbowstream)! Anyone up for checking the last boxes? 😀
