CSPACE-514 added javadoc plugin to pom.xml (trunk and main levels only). complete javadoc is created (later on config for public only). also added doc target for build.xml (trunk and main levels). the ant target also jars up javadocs. the dist targets in both trunk and main now dist javadoc jar as well
mvn javadoc:aggregate (to generate javadoc only)
ant doc (calls javadoc:aggregate and jars up the javadoc)
ant dist (now copies javadoc jar to dist)
