Updated candlepin has new logs location

Development

Just FYI: whereas previously logs were being written to
/var/log/tomcat6/catalina.out, they're now being written to
/var/log/candlepin/candlepin.log

If you've updated candlepin recently you may also need to run:

sudo service tomcat6 stop && sudo /usr/share/candlepin/cpdb --drop --create
&& sudo service tomcat6 start
