Issue

The README.md has a links and mentiones to the Arch Linux AUR package tizonia-all:

[tizonia-all](https://aur.archlinux.org/packages/tizonia-all/) [...]
[...]
- [tizonia-all (for the latest released version)](https://aur.archlinux.org/packages/tizonia-all/) 
[...]
```bash
# For the latest stable release
$ git clone https://aur.archlinux.org/tizonia-all.git
$ cd tizonia-all
$ makepkg -si
```

which does (not anymore) exist.
Only tizonia-all-git still exists.

The references to tizonia-all should be removed.

Regards!
