Fix the duplicate config by replacing `config` with a symlink. `config`
only exists for the `conf` function in zsh.
Remove *.font since it is overriden by the Xresources setting.
TODO: Keep rofi form reading the Xresources file?
Remove *.lines setting, since it is overridden by window.height.
Convert spaces to tabs.
Add Vim like keybindings for navigation.
Set matching-type to fuzzy.
Remove unused commented lines.
Remove ": " from prompts since rofi adds them already.
Change order of yes and no when conforming so that <Enter> cannot
accidentally be pressed twice.
Use tabs instead of spaces.
Replace all occurrences of [ with [[ in bash and zsh scripts and
configs.
Performance wise it makes sense to use the builtin instead of calling an
external command also when from a functionality stand point `test` would
suffice.
