ec2 port change + bug fixes

1. change port to 80 in server.js
NOTES: 
    sudo grunt server                 -to run server (port 80 requires root access)
    for EACCES, EADDRINUSE errors when testing the app remember to run
    sudo killall -9 node
    sudo killall -9 grunt
    before running server

2. Removed localhost from all backbone model routes. When running from the ec2 localhost no longer refers to ec2, refers instead to your local machine

3. fixed signup.hbs 'create account' button's id, changed signupView.js to reference #signup button

4. Commented out livereload (not compatible on ec2)

5. removed console.logs from router

6. added bower to dependencies instead of dependencies for heroku, changed procfile for heroku, added heroku grunt task

7. deleted unnecessary JQuery CORS file
