    Change default file system to ext4 (#711114)
    
    In the Create New Partition dialog use ext4 as the default choice for
    new file systems.  It has been the preferred file system of
    distributions for many years.  Use ext3 and ext2 as second and third
    choice defaults.  This handles RHEL/CentOS 5.x which doesn't support
    ext4.
