version bump: 0.13.0
replace tilestacherc definition with lwrp: tilestache_cfg
new lwrp does not take any action wrt restarting services: this moves the onus of restarts into the wrapper cookbook, e.g.
  tilestache_cfg '/some/path/to/my/config' do
    owner 'joe'
    group 'smith'
    mode 0660
    source_file 'my_template.conf.erb'
    source_cookbook 'my_tilestache_wrapper_cookbook'
    notifies :restart, 'service[tilestache]', :delayed
  end
