Update jbosstools bpel to include newer eclipse bpel and include in IS

If you look here:

[1] http://download.jboss.org/jbosstools/updates/stable/kepler/integration-stack/bpel/1.2.101.Final/

Then you'll see that this update site is a superset of the eclipse bpel update site. The JBTIS TP pulls in just the eclipse.org mirror (1.0.4) where the JBTIS aggreegate pulls in jbosstools bpel. This (jbosstools-bpel) needs to be rebuilt - it will pick up the usage parameter and it needs to pick up 1.0.4 of the eclipse bpel.
