Testing Done:

This patch adds support for mako style templates.

Example:
% for v in [20,30,40]:
auto vlan${v}
    iface vlan${v} inet static
    address 10.20.${v}.3/24
    mstpctl_ports  glob swp1-52.${v}
    mstpctl_stp on
% endfor

open items:
    - currently templates will only work if python-mako is installed
      (Its apt-gettable from debian wheezy).
