[PATCH] I've fixed bug #590.

[Konrad Kleine (none)]

The fix removes all non-shell logfiles from the
~/.sugar/default/logs directory (as usual) and keeps
the ten most recent shell logfile.

The backed up shell.log files carry their creation time as an
additional extension to their filename (e.g. shell.log.1180272197)
