[fixes lh 187, lh 240] refactoring eclipse support using sbteclipse-2…
….1.0-M2 this is the first few fixes based on the fully configurable version of sbteclipse. - target folder is now set to .target - java projects now have java builder in .project file (scala nature is removed) - java projects include scala-library.jar - java projects include classes_managed - scala projects include src_managed/main - scala projects use the IDE supplied scala container for allocating scala-library.jar
