example/hello_me.js: set all.js according to the README

This commit fixes two errors:
1. all.js was said to be in connect.facebook.com/en_US/all.js
   instead of all.js
2. the all.js script in the index.html was unecessary, as
   the hello_me.js generated from hello_me.ml, dynamically
   set that in the dom.
