separated connect and livereload tasks in devDependencies and Gruntfile

For some reason connect-livereload wasn't working. I'm on Windows 7. I kept getting a "connect:livereload task does not exist" warning. 

Installing grunt-contrib-livereload instead of connect-livereload in the devDependencies of the package.json file, and then separating the "connect" and "livereload" tasks in the Gruntfile solved this issue.
