Sample crontab maintenance script will delete files in $BASEDIR/public_html

[ericfung]

In Sec 2.9 (Maintenance) of the BuildBot Manual, there are sample crontab entries to manage the status and log files for builds. This sample entry:

@weekly cd BASEDIR && find . -mindepth 2 -type f -mtime +14 -exec rm {} ;

has the potential to delete files in the $BASEDIR/public_html directory since public_html is at the same depth as the build directories where logs are kept.

@weekly cd BASEDIR && find . -mindepth 2 -path './public_html/*' -prune -o -type f -mtime +14 -exec rm {} ;

should work better -- patch committed.
