Error handling has been reworked to always go through the new `error_template`, `error_json` and `error_atom` macros. They all accept a status code followed by a string message or an exception object. `error_json` accepts a hash with additional fields as third argument. If the second argument is an exception a backtrace will be printed, if it is a string only the string is printed. Since up till now only the exception message was printed a new `InfoException` class was added for situations where no backtrace is intended but a string cannot be used. `error_template` with a string message automatically localizes the message. Missing error translations have been collected in https://github.com/iv-org/invidious/issues/1497 `error_json` with a string message does not localize the message. This is the same as previous behavior. If translations are desired for `error_json` they can be added easily but those error messages have not been collected yet. Uncaught exceptions previously only printed a generic message ("Looks like you've found a bug in Invidious. [...]"). They still print that message but now also include a backtrace.
