baseproc16-default/theme_qutebrowser
Marty Oehme ae34a9c94d Add qutebrowser processor
Will switch colors for running qutebrowser instance.

Will add `colorscheme.py` into default qutebrowser config directory and
make sure the file is sourced from default qutebrowser config file
`config.py`. This makes the theme change permanent.
