JBTIS-225 - new bpmn2 + new .Final JBossTools core/coretests for JBTIS TP
create placeholder site for JBoss Tools 4.2 dev milestone for Luna so there's a valid URL from which to ping Central. Note that doing this means we have by default (until replaced) a site which is essentially identical to the one used by JBoss Tools 4.1.1.Final for Kepler SR1
release 4.40.0.Alpha1 target platform to targetplatforms/jbosstoolstarget/luna/ as latest stable one
add placeholder sites for updates/development/luna/ and updates/stable/luna/ (empty sites)
