Further cleaning of code and more comments, maven now pulls tika and droid automatically when clean installing (Caliper and Jhove do not have 'maven repositories'). Some new modes for TikaBench to print body and format metadata by mime-type. Javadoc integration with maven plugin added, use mvn javadoc:javadoc. Also minor version change for Droid (off the bleeding edge to 6.1.3 release) and Tika (Moved up to 1.7-SNAPSHOT).
