jbosstools integration tests site depends on itself to build; site is not self-cleaning

I've found some problems today:

1. building JBT integration tests requires the JBT integration tests site [circular dependency]

 [INFO] Adding repository http://download.jboss.org/jbosstools/updates/nightly/integrationtests/4.3.mars 

2. nightly 4.3.mars site [0] contains both Beta2 and CR1 bits, even though it's just the 4.3.mars site and should therefore only have Beta2 bits (CR1 should only be in master site [1]

[0] http://download.jboss.org/jbosstools/updates/nightly/integrationtests/4.3.mars/
[1] http://download.jboss.org/jbosstools/updates/nightly/integrationtests/master/

3. each time a new build is published into /updates/ [2], [3] it does NOT clean out the old releases, so the site is unnecessarily cluttered with old, orphan artifacts.

[2] http://download.jboss.org/jbosstools/mars/snapshots/updates/integration-tests/4.3.mars/
[3] http://download.jboss.org/jbosstools/mars/snapshots/updates/integration-tests/master/

4. The above sites [2], [3] contain content from BOTH branches, which is why we have artifacts from B440 (master) and B25 (4.3.mars) at the same time.

5. The check that the build does to determine if it should publish the new bits is failing to find the check script.

6. There are two different URLs [0], [2] being used for publishing bits, but the contents appear to be identical.

[0] http://download.jboss.org/jbosstools/mars/snapshots/updates/integration-tests/4.3.mars/
[2] http://download.jboss.org/jbosstools/updates/nightly/integrationtests/4.3.mars/

This is because we have symlinks:

updates/nightly/integrationtests/4.3.mars -> ../../../mars/snapshots/updates/integration-tests/4.3.mars/
updates/nightly/integrationtests/master -> ../../../mars/snapshots/updates/integration-tests/master/

So this is OK but we should migrate to use the new correct URLs instead of the old ones.
