Change colors 8 and 15 to necessary grays
Change colors 8 and 15 to necessary grays

I no longer rely on base16-shell to set colors 16-21, so that I can rely
fully on just 16 colors.

However, now I have less space for my range of grays; I can really only
afford one shade of gray (color 8, bright black).

However, a lot of my setup relies on two shades of gray (one for fg, one
for bg) to mute certain elements into the background. So, I've
repurposed color 15, bright white into my fg gray while color 8, bright
black will remain my canonical bg gray.

This is a coordinated change across a lot of my config repos; my Vim
colorscheme, ZSH prompt theme, and Tmux colorscheme have all been
updated.
