[Live-demo] change Geomajas version

[Matthias Streulens Geomajas]

Hello,

today I make a pull request for change the Geomajas version to 2.4.0.
Also I changed the shared shapes path that was wrong in the previous 
release.

I saw also a commit 11 days ago to change to Tomcat 7.
I must say that our example is deployed with Jetty standalone.

Where is the Google Docs sheet where I can change the Geomajas version?

Can someone merge the pull request so I can test tomorrow the nightly 
build of the dvd?

Kind regards,
Matthias
