Post commit hook for www.xfce.org not working

[Jérôme Guelfucci]

Hello,

The post commit hook for www.xfce.org does not seem to be working, after 
a commit I can't see my changes on mocha.xfce.org, but when I asked 
Jannis to update the sources manually, they appeared.

It would also be great to have a commit hook for the devel branch of the 
website sources, so that I can use www-test.xfce.org to show some mockups.

Thanks,

Jérôme
