Should hopefully help resolve #1116

URL names (for stats) were not HTML-escaped in the dashboard.
This made names with angle brackets disappear. For example:

```
self.client.get(url, name='/some-resource/upload/<uuid>')
```

would show up as `/some-resource/upload/` instead of `/some-resource/upload/<uuid>` which is confusing.

I added new key to /stats/request - "safe_name" - so that escaping
is on the server side and javascript has less logic.

Actually cgi.escape is still available in Python3.7, but is deprecated.
So going forward, it's safer to import escape from html.

I disabled escaping quotes (quote=False) for consistency and because
it's not needed for this purpose.
