v. 0.5.9.2
By default, do not install 'os-prober' or 'xf86-video-vesa' anymore.
Changed order of steps 'configure_system' and 'install_bootloader'.
The installation of packages is now grouped together like so: base,xorg,additional packages.
This allows additional packages to be available at the 'configure_system' and 'install_bootloader' steps.
