Description of problem:
The ant 'clean' task calls clean-deploy-[appname] on each app listed
in project.xml. This will delete from the WEB-INF/lib and either ROOT/
or [appname]] directories. There are a number of problems with this:

* WEB-INF/lib is shared, so it causes other application's files to be
removed
* ROOT is shared, so again more than just that application's files are
remove.
* If you change the webapp that an application is deployed to, run
ccm-configure.sh & then run 'ant clean' the old deployment directory
will never be cleaned up

The per-application clean-deploy-XXX targets should just be combined
into a single 'clean-deploy' target that removes the entirity of
$CCM_WEB_HOME/webapps.
