[examples] Use CCD for example scene

[bakpaul]

Use the CCD collision detection in the example scene to remove the bad looking skinning effect (not very good for showcasting).

The downside is that we have a 20% reduce in performances (on my computed we went from 240 fps to 190)

It would be nice to have a dedicated scene example for CCD
Moreover, your change added a warning in the scene :

[WARNING] [CCDTightInclusionIntersection(CCDTightInclusionIntersection)] Required data "alarmDistance" has not been set. Falling back to default value: 1
