Added BlockDevice.largest_free_space and BlockDevice.free_space (iterator). Also added additional supported filesystems to parted. Apparently the online manpages doesn't agree with the local manpages, my previous statement that these gets ignored is false so added those in and removed some that isn't supported by my local manpages, 'ufs' for instance.
