include SwitchYard 0.4.0 in JBT SOA Tooling site

As per comments in SWITCHYARD-623, to add SwitchYard 0.4 to the JBT SOA Tooling aggregate, you must add the new folder [0] to the composite by editing these files [1] so that the SOA Tooling site build can resolve the new content (that is, the switchyard feature listed in site.xml [2] can be found while building:

[0] http://download.jboss.org/jbosstools/builds/staging/SwitchYard-Tools/
[1] http://anonsvn.jboss.org/repos/jbosstools/trunk/download.jboss.org/jbosstools/builds/staging/_composite_/trunk/compositeArtifacts.xml, compositeContent.xml
[2] http://anonsvn.jboss.org/repos/jbosstools/trunk/build/aggregate/soa-site/site.xml

Then, respin this job [3] to verify the site's been updated correctly [4].

[4] http://download.jboss.org/jbosstools/updates/nightly/soa-tooling/trunk/

Repeat for [5] and [6] – need a second job for 0.4.0 as it stabilizes for Beta1 inclusion while trunk work continues (eg., toward 0.5.0).

[5] http://download.jboss.org/jbosstools/builds/staging/SwitchYard-Tools_stable_branch (or equivalent name)
[6] http://anonsvn.jboss.org/repos/jbosstools/trunk/download.jboss.org/jbosstools/builds/staging/_composite_/3.3.indigo/compositeArtifacts.xml, compositeContent.xml

You'll then want to add the new job [5] to this view [7].
