and fix a few things :)
Although I'm in the tabs camp, Smack uses mostly spaces. Therefore it is the logical choice for the indentation style.
- Lines containing tab(s) after space - Usage of printStackTrace - Usage of println - Add SupressionCommentFilter module SuppressionCommentFilter can be enabled with // CHECKSTYLE:OFF and disabled with // CHECKSTYLE:ON
Also renamed package name from org.jivesoftware.smackx.jingle to org.jivesoftware.smackx.jingleold
