Sanitize username and photo URL
HedgeDoc displays the username and user photo at various places by rendering the respective variables into an `ejs` template. As the values are user-provided or generated from user-provided data, it may be possible to inject unwanted HTML. This commit sanitizes the username and photo URL by passing them through the `xss` library.
