refactored Maven project hierarchy by introducing new top level folders ("releng", "devtools") and converting "sculptor-generator" into  an aggregator project; instead of "sculptor-parent" now "releng/sculptor-distribution" is used to build Sculptor; added new Maven project "sculptor-generator/sculptor-generator-library" to provide a single JAR of Sculptors code generator; added all Eclipse bundles needed for running Eclipse JDTs code formatter to Sculptors internal Eclipse library
