v. 0.5.7
Renamed variable "user_name" to "username".
Check if mkfs utilities are installed for all fstypes besides extfs.
Removed variables "install_desktop_environment" and "install_display_manager".
To skip installation of a desktop environment (display manager) set "desktop_environment"
to 'no'.
For manual partitioning, and if a seperate boot partition is present, determine the variable
"fstype" by the filesystem of the partition /mnt/boot instead of /mnt. The filesystem used
 for /boot must be supported by the bootloader.
