updated readme doc with grunt-cli dependency
updated .gitignore for mac files which love to sneak their way into repos
Moved express to 'server' directory
Updated gruntfile static asset locations to match
Hoping I didn't break anything. So far, so good.
added password-oauth npm dependency
also needed passpor as a dep, even tho github passport already defines it as one
updated gruntfile for github creds
github oauth code in place.
Something I did works, which is pretty sweet
