fix #35 : remove use of job to modify classpath
format
remove catalog.xml
set version 0.5.1
add info (to be able to test scala-ide version for specific behavior). Currently no special behavior if scala-ide.version >= 4.0.0 , the auto-detection of scala-library into maven container doesn't seems to work.
prj-scala-only: update to scala 2.10
restore deprecated use of AbstractJavaProjectConfigurator to keep build (with indigo)
update README
