Merge pull request #80 from retr0h/memcached

python-memcached needs installed on everything
Added VNC files to patch

Currently the novnc package has a bug, which doesn't load the websockets
code when running on port 443 or 80.  Committing the troublesome code, and
will patch in a separate commit.

This is a temporary fix, and future openstack builds, should pull in
a more recent novnc package.
Patched novnc code to handle port 443 and 80

We were able to run novnc if it were on a port other than 443/80,
otherwise it would hang with "loading" text.  This bug was corrected
upstream, a few days ago.  We are likely not to see this fix get
into opentstack repos for quite some time (if ever in folsom).
