MODE-1925 - Fixed the packaging and dependency versions of the demos which are part of the main ModeShape distribution.

The problems ranged from the running scripts (which contained type-o-s) to the fact that ModeShape was using an old version of `jboss-logging`. Since ISPN directly uses the same artifact, we need to make sure that we at least use the same version as ISPN (or a newer one, if it's compatible with EAP).
