Allow ErrorInfo messages with formatArgs

- ErrorInfo.getMessage() now returns an ErrorMessage instance that can be formatted into a string using a context (this allows the construction of an ErrorInfo to remain independent of a Context)
- now the service ID is used in ErrorInfo.getMessage() to customize some messages based on the currently selected service
- player HTTP invalid statuses are now included in the message
- building a custom error message for AccountTerminatedException was moved from ErrorPanelHelper to ErrorInfo
