Space keeps its scans and refreshes them: zfs diff, folder mtimes, resume after cancel

Browse Source 
A scan is saved beside the config and read back after a restart. The next scan starts
from it: on a pool with snapshots zfs diff names what changed and only those folders are
read; elsewhere a folder whose mtime is unchanged keeps its list and only its kept files
are stat'ed again. A cancelled scan keeps what it walked and Resume reads the rest.
Forget drops the saved result. The treemap is every file a tile, grouped by folder, with
no nested boxes: the folder chains of a Linux system made a staircase of empty headers.
