Noticed rofi wasn't handling selection highlights properly any more. In
troubleshooting found the stylesheet was massively over-complicated
since it was a copy of a less simple stylesheet in its origins.
Simplified and fixed the bug.
- Switch to a base16 builder wrapper I wrote myself
- Switch small details on a bunch of templates
- Switch to a QVP based color scheme I wrote myself
This should form the most rational default for colors going forward.
This is the result of using [base16](https://github.com/chriskempson/base16).
The first crack at establishing a base16 theme here is based on irblack
with a slight modification to make text selection purple and make rofi's
template less ridiculous.
Also added .Xresources and qutebrowser to management, and added the
resulting vim themes directly to management as well.
