nginx reports 403 error because of static dir permissions

[Matthew Mosesohn]

In /var/log/docker-logs/nginx/error_nailgun.log:
2014/10/14 08:49:53 [error] 372#0: *57 "/usr/share/nailgun/static/index.html" is forbidden (13: Permission denied), client: 172.17.42.1, server: localhost, request: "GET / HTTP/1.1", host: "10.20.0.2:8000"

We should set permissions for files inside /usr/share/nailgun/static to 644.

    Set permissions on nailgun files installed

    Includes a workaround in nginx start.sh script to
    reset permissions on /usr/share/nailgun/static
    because Docker resets it to 700.
