Download easyb JAR file with all dependencies

This composite contains a restricted version of easyb-core, so that people can depend on named releases of easyb without having to keep a version range of easyb-core if they so wish. It provides compatibility with existing uses of easyb, and easyb versioning (0.9x). It is *recommended* that people stop using this artefact and instead use the easyb-core with a version range of [1,2] so updated bug fixes and feature releases flow in.
