Fix error when including tutorials #51

Adding check for existence of ancestors property on item before reading ancestors.length. The ancestors property does not exist on tutorial items so the build breaks with the following error:

C:\dev\projects\stuff\node_modules\docdash\publish.js:335
      if (item.ancestors.length > level) {
                         ^

TypeError: Cannot read property 'length' of undefined
