Method refining

Now using the product-tile.html on 4 pages: home, product, category, and search

To do this I needed to have translation routed in app.js to all those templates. I think it would be easier to make product tile a directive and declare translation in that single section. Let me know what you think about refactoring here. Currently product-tile is just using an ng-include.  Thanks @hippee-lee @prabinv
