Fix "ant test" + misc clean up / reorganization of build.xml
- Split NewSetupTask in several tasks to make things more flexible.
Particularly this allows more targets to get access to the project
type (app, lib, test, ...) as it's not so computive intensive.
- Fix test project to give them access to the full tested project's
classpath.
- Fix support for projects that test themselves.
- Make sure library projects are instrumented when using the
emma target.
