update less build (see message)
Remove "grunt less" task and have the less build-out run via shell commands set up via "grunt shell". In package.json, add the "gulp shell" task and remove the "grunt less" task. Do the same add/remove thing in Gruntfile.js. Make "grunt gulp" run the new "grunt shell" task in gulpfile.js. Update Gallery styles.
