Fixed CSS to use img-responsive class properly. Fixed Gruntfile to build POT file without throwing warnings. Fix multiple in-content media inclusions that specify/expect invalid image sizes to use 'large' instead.Added data-template attributes to several templates to help identity template parts easier on front-end. Fix double-loading of require.js and add theme-version to app.js for cache-busting. Changed Featured Listing Post and Advanced Gallery modules to use the native wp_get_attachment_image_src method for getting image URLs and set size to 'medium'.
