remove quotes from a posts meta description (IMPORTANT: see msg)

There are quotes in the meta description for the post file '_posts/2010-12-03-cnn-calls-track-option-google-killer.md.' This disrupts Grunt when it minifies HTML in the '_site/' directory with the 'htmlmin' task. remove quotes and stop putting them in meta descriptions moving forward.
Major Gruntfile.js updates (see msg)

add 'grunt-jekyll' and 'grunt-contrib-htmlmin' to the file. create 'grunt watch' task to watch HTML, image, .css and .js changes. create 'grunt push' task to 1) minify all site content, 2) build related posts links for all posts with Jekyll LSI build config and 3) deploy to the site. Make sure that '_site/' directory is not tracked. Update 'package.json.'  TEST EVERYTHING!
