Review Eclipse BPEL 0.5 for inclusion in JBT/JBDS

Because both Savara and JBoss BPEL depend on Eclipse BPEL, we need to be consistent w/ the version used.

Currently, we just source from here [1].

[1] https://svn.jboss.org/repos/jbosstools/trunk/bpel/pom.xml

I would need to:

a) pull a mirror of BPEL @ Eclipse to here [2], like we do with Indigo, EMF, Eclipse, SWTBOT, BIRT, etc.).
b) add it to the TP files [3] and respin them
c) have you both pull from the same version of Eclipse BPEL

[2] http://download.jboss.org/jbosstools/updates/requirements/
[3] https://svn.jboss.org/repos/jbosstools/trunk/build/target-platform/

Only wrinkle here is that we won't be able to respond as quickly to new BPEL releases. We won't be pulling nightlies anymore.
