Revision 162756

o added project.build.output which takes a default value of
  target/classes and is the location for compiled application classes

o added project.build.testOutput which takes a default value of
  target/test-classes and is the location for compiled test classes

  After chatting with Michal we decided that we want a single place
  where we can control these values and provide a single place for
  a user to override them if they wish to.

  The build directory, the directory where compiled app classes go, and
  the directory where compiled test classes go can now all be accessed
  in a consistent fashion.
