CSPACE-643 build now requires the following properties set in the environment.

CSPACE-643 build now requires the following properties set in the environment.
DB_USER, DB_PASSWORD (for create_db, gen_ddl tasks) and JBOSS_HOME (for deploy)
Each build.xml reads environment before loading build.properties. build.properties uses environment variables to set db.user, db.user.password and jboss.dir properties.
Database and user specific properties are also externalized from hibernate.cfg.xml used by gen_ddl task. Before invoking gen_ddl subsitution occurs as a pre-requisite.
tests: mvn test at services level, ant create_db at trunk level, gen_ddl at account and authentication client levels
