Temporary working LiveReload

LiveReload works when typing 'gulp' in CMD. Code needs some clean-up
though.
Doing code clean-up...
Live Reload moved to rocket.js

Moved the files from gulp.js to rocket.js for live reloading the browser
using middleware called connect-livereload.
Live Reload external

Moves the livereload code from rocket.js to an external file called
livereload.js in the developer folder. Also updated the package.json
file by setting the main file to rocket.js. Now in the command line,
type node rocket to initialize server and app.
Finish Live Reload
