Modify ant targets and align them with maven build profiles

As per a discussion on the list the following changes need to be made to the ant targets as well as introduce a new maven profile called 'package'

• ant verify == mvn clean verify
  • This would compile, run unit and surefire based functional tests.

• ant package == mvn -Ppackage clean install
  • This would compile, run unit and surefire based functional tests and create binary packages
  • This could be followed by 'ant install-test-home' or combined 'ant package install-test-home'
  • IMPORTANT: This would be the gating criteria for a commit

• ant release == man -Ppackage,release clean install
  • This would compile, run all tests (including failsafe based integration tests) and create binary package.
  • This would be the job run on the Jenkins servers.
