Switch EVERYTHING to using base16

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.

.Xresources
