Java client updated to not use goofy keystores

[Bryan Kearney]

I was hitting some client bugs, and the java client was failing because 
of the new keystore format. I pushed a change that it now uses the PEM 
encoded Crt file. The new config file should look like:

serverURL=https://localhost:8443/candlepin/
candlepinCertificate=/etc/candlepin/certs/candlepin-ca.crt

BTW... if you haave ever thought the Calendar API sucks for java.. you 
should look at the SSL API. Good G*D.
