Fix confluence source release

A few bugs with our current source release:

1. the modules such as "tomcat_env_confluence-webapp" have a dependency to "confluence-webapp", which does not exist (only the confluence module is created)
2. the default.properties file does not get populated correctly (version number, partner name etc)
3. the server.xml for tomcat has the wrong webapp path (because we removed that extra confluence directory)

I have confirmed this for 2.3.2 and 2.4
