Package updates in yay (as in pacman) will not be reported correctly
when the repository mirrors have not been updated recently.
However, updating only the mirrors without also synching the packages
locally is not recommended by arch. That means, essentially, we can't do
a dry-run to only 'check' for packages without running the danger of
performing a partial arch upgrade.
The program `checkupdates` in pacman-contrib package helps with this by
performing a check for the available updates without needing to pull
from the mirrors before. So, the polybar update script now checks for
its existence and uses it if available, falling back to the standard yay
procedure otherwise.
Makes polybar use Xresources color values for its colors. Resets rofi
values to their default after being overwritten by the base16 themes.
Makes qutebrowser include the colorscheme in its configuration file.
Ignore dynamically generated colorschemes in .gitignore file.
