[Pharo-dev] Support for demos

I’ve added an up to date build of a Pharo 3 version of the workshop image I’ve used at FOSDEM. The workshop itself was given with a Moose 5. Please feel free to (re)use. https://ci.inria.fr/pharo-contribution/job/Forum/ In a workspace, do FOTutorial open for the participant version and FOTutorial openPresentation for a presenter version with larger fonts. To see some roassal visualizations related to code quality, do FOBrowser open Stephan More tutorials, with exercises integrated in the tutorial browser, can be found in http://ss3.gemtalksystems.com/ss/SpaTutorial
