added ubuntu-13.10 packer templates w/debian sudoers scripts

I pointed this to "scripts/debian/sudoers.sh", and put the boxes through basic tests.  VMware needs some HGFS kernel love (as I believe is mentioned on tickets.opscode), but this fixes the sudo issue, and I can su up to root w/o a password as expected.

VMware:
The HGFS kernel module was not found on the running virtual machine.
This must be installed for shared folders to work properly. Please
install the VMware tools within the guest and try again. Note that
the VMware tools installation will succeed even if HGFS fails
to properly install. Carefully read the output of the VMware tools
installation to verify the HGFS kernel modules were installed properly.
