Bug 959844 - JBoss EWS v2 Cartridge fixes for EWS1.0

https://bugzilla.redhat.com/show_bug.cgi?id=959844

The JBoss EWS v2 cartridge previously advertised EWS1.0 support without
requiring tomcat6 be installed, so if the v2 cart was installed without
also installing the v1 EWS1.0 cart, EWS1.0 support would be advertised,
but created apps would fail.
