Alex Vandiver 1833afee6a js: Enable cross-origin error debugging with crossorigin="anonymous". ...

If the script comes from a different origin than the requesting page,
and is not marked `crossorigin="anonymous"`, the `window.onerror`
handler receives no information other than "Script error." in the
event of a runtime error.

This effectively silences blueslip errors in development if the user
is developing on a remote host (such as a DigitalOcean droplet), since
static resources are served from `hostname.zulipdev.org`, and the
realm is served from `realmname.hostname.zulipdev.org`.  It also
silenced blueslip reporting in production for any non-default (non-"")
realms.  Sentry reporting, Vagrant developments, and truly ancient or
insecure browsers were unaffected.

Add the necessary `crossorigin="anonymous"` attribute to the
`<script>` tag to allow blueslip access to this error information.
