catalina bundle output is not cleaned

SourceForge Submitter: doogie .
When optional modules are enabled(by doing
-Dgroups=all), the bundle directory for catalina is not
cleaned. So, when the source tarball/zip is built, it
happily includes
catalina/output/jboss-$

/, which is a 43
meg directory. This increases the size of the
distribute source file by more than 20 megs.

The attached patch adds a dep to the clean target to
remove this directory. The only downside is if you
don't call clean with the same set of modules as you
built with, then catalina won't be built.

Maybe cleaning should always traverse ALL modules, not
just the ones that have been selected with -Dgroups.
