javascript/README incorrect

[George Ruban]

The 
javascript/README<http://svn.apache.org/repos/asf/incubator/shindig/trunk/javascript/README>that
new developers are pointed to from the Apache Shindig front page seems
to be wrong.
At least I can't get anything useful following its instructions, while I can
by navigating to
http://localhost:8080/gadgets/files/container/sample1.html(and so
forth) directly.
