Use Ivy as foundation for libmanagement tool

Ivy is non-intrusive, ant and maven compatible and it is very pluggable.

For libraries there does not exist pom's/ivy-xml we can create them and have an rhds-ivy lib, it handles multiple configuration (usefull for hibernate) and it supports just copying to local lib dir ...all good.

main site: http://incubator.apache.org/ivy/
classpath container in eclipse: http://incubator.apache.org/ivy/ivyde/cp_container.html (right direction, but needs more)

still not solved:
how to handle related javadoc and source attachements ?
