Script for installation of dependencies

[alisinabh]

It would be awesome if there would be a script helping installation of the following dependencies:

• qrencode
• imagemagick
• zbar
• Maybe a default font

This script should be able to determine OS type and install the packages preferably using a package manager (like apt, pacman or homebrew).

For the installation of zbar, this script should check for minimum required version because many package sources still use old versions of zbar (especially in Ubuntu and Debian sources)
