support soa tools job name conventions when generating build ID for index.html pages (JBT & JBDS sites)

Before:

http://www.qa.jboss.com/binaries/RHDS/builds/staging/devstudio-5.0_stable_branch.soa-tooling.updatesite/product-soa/
devstudio-5.0_stable_branch.soa-tooling.updatesite -> 5.0.0.v20120430-1318-H279-Beta2.soa-tooling

http://download.jboss.org/jbosstools/updates/nightly/soa-tooling/trunk/
jbosstools-3.3_trunk.soa-tooling.aggregate/ -> 3.3.0.v20120430-1651-H1254-CR1.soa-tooling

After:

http://www.qa.jboss.com/binaries/RHDS/builds/staging/soatools-5.0.0.Beta1--JBDS-updatesite/product-soa/
soatools-5.0.0.Beta1-JBDS-updatesite -> soatools-5.0.0.Beta1-JBDS-updatesite (no pattern matched)

http://download.jboss.org/jbosstools/builds/staging/soatools-3.3.0.Beta1--aggregate/all/repo/
soatools-3.3.0.Beta1-aggregate -> soatools-3.3.0.Beta1-aggregate (no pattern matched)

Files to fix:

https://svn.jboss.org/repos/devstudio/trunk/product-soa/site/build.xml
http://anonsvn.jboss.org/repos/jbosstools/trunk/build/aggregate/build.xml (lines 528-531)

Look for lines like this, and add additional regex matches:

<propertyregex override="true" property="update.site.version" .../>
