basically, I:

- updated all infrastructure to Pharo 3 (I do not want to let our tools to become too old)

- added a commit hook mechanism (still need to be tested)

- added a small app to list all projects (which is still not working)

so��� none of the visible changes can be seen now, but if everything goes fine��� it will be in a couple of weeks (before Pharo4 release)
