rofi: Fix duplicate, whitespaces, bindings & more

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.
