move to jquery-1.11.1, which fixes the CSP violation

1.11.x moved the generated jquery.js from the top level to
dist/jquery.js, so this also updates the paths in app/scripts/main.js to
match.

add Content-Security-Policy headers when in dev mode

When this is active, the server accepts violation reports via POSTs to
/_/csp-violations, and the CSP header points to that URL, so devs can
see problems immediately.

The patch also includes a small standalone reporting server which can be
used as the target of externally-added CSP headers (e.g. when nginx is
configured to add them). Staging/production deployments will use this,
instead of the built-in endpoint.
