make jboss tools maven facet generate a "good" pom.xml

currently we generate a very custom and not at all clean pom.xml with context of dependenciees and setup when using jboss maven facet.

This pom.xml should:

A) be clean

B) not add dependencies against Project Wolf recommendations (should it have an "use enterprise" flag?)

C) make maven library provider work or remove/disable it so dependencies are clean.
