Moreover, generate "Light" colorscheme from "Dark" on install
by swapping monotone palette colors.
Fix global selection background to be consistent with specific styles.

Use base02 for the current line, and defaults to Consolas 9pt
Tweak a bunch of common highlighting schema
Typo
Tweak Bash highlighting some more
Some more highlighting tweaks
Tweak Makefile highlighting some more
