Adding Debian 6.0.7 i386 template. Builds tested.
Changing Debian checksums to sha1.
Adding vmtools script to Debian.

Also changing the shutdown command to be more inline with others as it
does not seem to timeout for me anymore especially when I build each box
individually using Packers's -only flag.

I'd missed out the vmtools script and until a concrete decision on
installing Chef is made I matched the other templates by including the
chef_omnibus script.

Also changed the order of the scripts to match the other templates.
