This adds a severity field to Error objects. This can be used to detect whether an error is recoverable. All the same errors are still reported so the field can be ignored. There are two possible values: * RECOVERABLE means that the Player will try to recover from the error * CRITICAL means the Player will be unable to continue and must call load() again Closes #564 Change-Id: Ie2c5468340c13e7a288b99690ab65b7ecc0a6b29
