- there is no official way to automatically filter mirrors by country and/or rank them in ArchLinux.
- this function was always exclusive to Manjaro and therefore useless for Arch
- there no reason to make the tab appears in Archlinux except if we add support for another tool like reflector.

- see also: https://github.com/manjaro/pamac/issues/258
- this is only needed for Archbased Distros like Antergos

The previous standard was to insert spaces around x = y. Not having those affects pacman-mirrors in certain functions the app is checking the config file if a change should be written to a specific line.

- this will dump min. vala dependency up to v0.36
