Added a vanilla Debian 6.0.6 box 32 bit

I've created the box using [this procedure](https://github.com/jedi4ever/veewee/blob/master/doc/vagrant.md) and used [this template](https://github.com/jedi4ever/veewee/tree/master/templates/Debian-6.0.6-i386-netboot) as base.

I removed the Debian chef package (pretty old) and puppet (not needed for me).
Added centos 6.2 and 6.3 32bit puppet boxes
removed explicit download query parameter
Update www/index.html

2 Boxes added at last row of file

Fixed broken minimal-wheezy link
Added CentOS-5.6 64bit with puppet & chef from RPMs
Update Oneiric links
Remove broken links for Oneiric
