Fixes #580.
This follows a recent change in WebKit (see https://webkit.org/blog/6830/a-refined-content-security-policy/, section "More restrictive wildcard *") to remove websocket schemes from the connect-src directive.
Users of Safari v10 (to be publicly released in a few days) would be affected by this and could not load the app.
Ping @Gilles123 to test this.
