Cleaning the stats directory

[Jeff Weisberg]

| a simpler way is to remove files that haven't been modified recently,
| since argus updates the statistics after running tests. Something like
| 
| find /var/argus/stats -mtime +1 -print0 | xargs -0 rm
| 
| is simpler than my last idea. It's also good in the gcache/gdata directories.


or you could just wait. argus will periodically look for and remove
any unused old files in the stats, gcache, gdata, and html dirs.
