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

Updated for High Sierra's terminal dealing with emoji better

Updated to get more in the spirit of things

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.
