-`Silent(bool)`            | If set to true, this prevents the handler from sending the error to Raygun, printing it instead.
-`Request(*http.Request)`  | Adds the responsible http.Request to the error.
-`Version(string)`         | If your program has a version, you can add it here.
-`Tags([]string)`          | Adds the given tags to the error. These can be used for filtering later.
-`CustomData(interface{})` | Add arbitrary custom data to you error. Will only reach Raygun if it works with `json.Marshal()`.
-`User(string)`            | Add the name of the affected user to the error.
