To complete the autoburt alog: how to restore from a snapshot file.

Just 'cd' into the directory containing the snapshot files to be used
for the restoration. Then use the 'burtwb' command, it takes the snapshot
file as an argument.

For example, burt restore g1isihamepics to 14:01 snapshot of jul 20th 2010:

[controls@seiteststand 14:01]$ cd /data/autoburt/2010/07/20/14:01/
[controls@seiteststand 14:01]$ burtwb -f ./g1isihamepics2010072014:01.snap
