ZSH prompt with finger guns 👉 😎 👉 (requires emoji support)

Finally took the time to figure out why shell completion was eating the end of the prompt: there's a bug in ZSH on mac that breaks COMPLETION_WAITING_DOTS.

ohmyzsh/ohmyzsh#6226

handy-vars.zsh isn't necessary so let's If it. (I keep stuff in there like TODAY=(date +%Y%m%d) to grease stuff like making temp files (touch tempfile-$TODAY.yaml or whatever) or other vars I want to update more often than once-per-terminal-session)

Fuckin' around to make it more readable. Now also solely reliant on built-ins.

Trying this out on a High Sierra machine... is it supposed to do anything besides fingerguns-up on shell start, and fingerguns-right after that? That's all I'm seeing. No thumbs down or other special effects.

@ejheil i think I had something else interfering earlier cuz i had the same behavior once i switched to a new machine. got it updated so it behaves better now, sorry it took so long to get back to you!

un-executed prompt, $? is 0: guns up (let's do this)
executed prompt, $? is 0: cool guy finger guns
$? is non-zero: angry thumbs down (i decided i didn't want that one to change so i don't erase the visual cue for a previously-failed command)

Works great now, thanks!

Today's update: 'refactor' the variable names so I don't do dingus stuff like overwriting something as heavily used as $USER.
All the internal variables are now prefixed with FG_ and USER in particular is now FG_USER_BADGE.

Hooray for scoping.
